Every statistical tool we make, in one licence Method validation with 11 CLSI protocols, diagnostic accuracy with ROC curves, survival analysis with Kaplan–Meier and Cox regression, statistical process control with Shewhart, CUSUM, and EWMA charts, plus the full general statistics toolkit — ANOVA, regression, PCA, and more.

Every feature from all five editions for 15 days, no sign-up.
Ultimate edition from US$ 575 a year · 30-day money-back guarantee.

Microsoft Excel with the Analyse-it tab of the Ultimate edition selected: a linearity report with the nonlinearity plot and its table, the MSA task pane open, and the whole Analyse-it ribbon with every command group of every edition. Handwritten notes: Runs inside Excel, and every edition includes the statistics research needs:; Ultimate adds them all: process control, Pareto, capability, method comparison, MSA, diagnostic accuracy, reference intervals, survival; Nonlinearity at each dilution with its 90% CI: plots and tables on a worksheet; Every option for the analysis is set here, then Recalculate; The output is an Excel worksheet: share it with colleagues, auditors or regulators, archive it, open it on any PC with Excel.

Most organisations don’t fit neatly into a single edition. The IVD company running CLSI method validation studies also needs SPC on the manufacturing line. The clinical lab verifying a new assay also runs survival analysis for research publications.

The quality team monitoring control charts also needs ANOVA and regression to investigate out-of-control events.

The Ultimate edition unlocks every feature across all four editions — Method Validation, Medical, Quality Control & Improvement, and Standard — in a single licence at US$575/yr, less than any two specialist editions bought separately. Already own a specialist edition? Upgrade for the difference in price.

We use Analyse-it frequently for our verification and pre-verification work, in accordance with CLSI guidelines for in-vitro diagnostics. It’s saved time and effort compared to the hodge-podge of applications we used before, JMP, SAS, etc…

Validate and verify measurement system performance

The complete CLSI method validation toolkit — precision, linearity, detection capability, method comparison, reference intervals, and diagnostic performance — with 11 evaluation protocols built in:

  • Precision with nested variance component designs — repeatability, between-run, between-day, within-laboratory and reproducibility — and precision profiles with seven variance function models (EP05-A3)
  • Linearity with polynomial and weighted regression, Hsieh-Liu nonlinearity testing against an allowable nonlinearity, and an adjustable measuring interval for reportable range determination (EP06-Ed2)
  • Detection capability — LoB, LoD and LoQ using parametric, non-parametric, probit regression and precision profile variance function approaches (EP17-A2)
  • Verification of precision and trueness against manufacturer claims — such as testing an observed CV against a claimed 3.5% — with χ² and equivalence tests (EP15-A3), and preliminary evaluation of precision and bias at three levels against allowable limits (EP10-A3-AMD)

Compare methods and evaluate the impact of changes

Five regression models for method comparison — including Passing-Bablok, Deming, and weighted Deming — plus Bland–Altman agreement and total analytical error:

  • Passing-Bablok and Deming and Weighted Deming regression with confidence intervals on the slope and intercept, and bias at medical decision points with equality and equivalence tests against an allowable difference
  • Bland–Altman limits of agreement — the bias as a mean, a median or a regression across the measuring range, with constant or non-constant precision and confidence intervals on the limits
  • Total analytical error per EP21-A — bias and imprecision combined and judged against the allowable total error, with the mountain plot of the differences
  • Commutability of processed samples and reference materials per EP14-A3 — compared against patient samples with prediction intervals
  • Qualitative methods — positive and negative agreement, and kappa and weighted kappa with linear or quadratic weights, for two methods with no known true state (EP12-A2)

Establish reference intervals for clinical interpretation

Full range of reference interval methods — match the method to your sample size and distribution, partition where subgroups need separate ranges, and transfer or verify intervals when moving to a new measurement procedure:

  • Five quantile methods — parametric, non-parametric (three computation approaches), robust bi-weight, bootstrap and Harrell–Davis — the right estimator for the sample size and the shape of the data
  • Partition by sex, age, ethnicity or any combination of factors — one report per partition, with the descriptive statistics and limits for each
  • Full range of transformations — log, square root, cube root, Box–Cox, Manly exponential, two-stage exponential/modulus — for skewed analytes, with the limits reported back in the original units
  • Transfer and verify existing intervals — a published interval checked against 20 samples with the binomial proportion test, or transferred by regression between procedures

Evaluate diagnostic test accuracy

Establish and compare the ability of a diagnostic test to discriminate between patients with and without a condition — and find the decision threshold that balances sensitivity, specificity, and clinical cost:

  • Empirical ROC curves per EP24-A2, with the area under the curve, its DeLong confidence interval and the test against no discrimination
  • AUC comparison (DeLong) for up to 10 paired or independent tests — the difference in AUC with its confidence interval, and equality, equivalence or non-inferiority hypotheses
  • Sensitivity, specificity, likelihood ratios, predictive values at a prior probability, and the diagnostic odds ratio — each with its confidence interval
  • Optimal decision threshold by Youden’s index, the point closest to (0,1), or the clinical costs of misdiagnosis — and the sensitivity and specificity at any threshold
  • Qualitative test evaluation per EP12-A2 — sensitivity and specificity with confidence intervals, and the difference between two tests, for a test read as positive or negative against a known state

Analyse time-to-event data with survival analysis

Estimate survival functions, compare treatment groups, and model the effect of covariates on the hazard:

  • Kaplan–Meier survival curve for each group with pointwise, Nair or Hall–Wellner confidence bands, and the censored observations marked on the curve
  • Median, quartile and restricted mean survival time for each group, each with its confidence interval, and the survival function as a table
  • Test equality of the survival functions with the log-rank, Wilcoxon, Tarone–Ware or Fleming–Harrington test — the weighting chosen for early or late differences
  • Cox proportional hazards regression — the hazard ratio for every term with its confidence interval, interactions between factors, and the baseline survival function

Kaplan–Meier survival curves for the same 30 brain cancer patients grouped by tumour grade, censored observations marked on each curve.

Monitor processes with control charts

Shewhart variable and attribute charts with automatic detection rules, plus time-weighted charts for detecting small, sustained shifts:

  • Xbar-R, Xbar-S and I-MR charts for continuous data; p, np, c and u charts for attribute data — limits from the data or from known process parameters
  • CUSUM, EWMA and UWMA time-weighted charts — for the small, sustained shifts that a Shewhart chart is slow to signal, with the decision interval or weight set in the task pane
  • WECO, Nelson and Montgomery detection rules, or a custom set — runs, trends, stratification and oscillation flagged automatically, each signal labelled with the rule it broke
  • Phases for before-and-after comparison — installation, qualification and production, say — each with its own control limits on the one chart
  • Stratification by operator, shift, machine, material lot or any factor — points coloured and labelled by the factor, so the cause of a signal is visible on the chart

Determine whether the process meets the specification

Capability and performance indices with confidence intervals and non-normal data handling:

  • Cp, Cpk and Cpm for the inherent capability of a stable process; Pp and Ppk for the performance actually delivered — each with a confidence interval, so a marginal index is read as such
  • Z-benchmark and sigma level, and the nonconforming units outside each specification limit — observed %, expected % and expected PPM
  • Box-Cox and power transformations for non-normal distributions — so the indices are computed on data that meet the assumption behind them
  • Histogram with the specification limits and a fitted normal curve, and a normal Q-Q plot with Lilliefors band — see whether the process is centred, and whether the data are normal

Focus improvement effort on the vital few

Pareto charts to identify the most frequently occurring defects and break them down by contributing factors:

  • One-way and two-way comparative Pareto charts — defect type by operator, shift, machine or product line, one chart per cell so the vital few in each are compared side by side
  • Merge low-frequency categories into one bar, reorder the bars by any key, and colour by subgroup — the categories table in the task pane, no data editing
  • Cumulative percentage line with each point labelled — the 80/20 cut-off read straight off the chart, bars labelled with their frequencies

Handwritten notes: One Pareto chart per cell: operator by training; Layout: matrix.
Two-way comparative Pareto chart: colorimeter failures for each of three operators, before and after training.

Compare groups and test for differences

Independent samples, paired samples, two groups or ten — parametric and non-parametric tests with the assumption checks built into the same workflow:

  • Student’s t, Welch’s t and Wilcoxon-Mann-Whitney for two independent groups; one-way ANOVA, Welch’s ANOVA and Kruskal-Wallis for three or more — with the homogeneity of variance tests that decide between them
  • Paired t-test, Wilcoxon signed ranks and Sign test for two related measurements; within-subjects ANOVA and Friedman for repeated measures on three or more occasions
  • Eight multiple comparison procedures — Tukey-Kramer, Dunnett, Hsu, Scheffé, Steel, Dwass-Steel-Critchlow-Fligner among them — to find which groups differ after a significant ANOVA, each controlling the family-wise error rate
  • Cohen’s d and Hedges’ g effect sizes with non-central t confidence intervals — how large the difference is, not only whether it is significant

Fit and diagnose regression models

Regression as a process of building, examining, and refining — not a single pass from data to p-value:

  • Simple linear, polynomial, logarithmic, exponential, power and probit regression — fit the curve the relationship calls for, with a confidence band on the fit
  • Multiple regression with continuous and categorical predictors, crossed terms and interactions — categorical predictors are dummy-coded automatically, one row per level in the estimates
  • Binary logistic regression for a yes/no outcome — the odds ratio for every predictor with its Wald confidence interval, and likelihood ratio tests for the model and each term
  • ANOVA and ANCOVA with crossed factors, interactions and continuous covariates — effect means, main effect and interaction plots, and multiple comparisons on the effect means
  • Residual diagnostics, leverage plots, Cook’s D influence and VIF for multicollinearity — the checks that show whether a model can be trusted before it is reported

Describe and visualise data

Every analysis starts with understanding the data. What does the distribution look like? Are there outliers? Is it normal?

  • Mean, median, SD, CV%, skewness, kurtosis, geometric mean, harmonic mean, quantiles and mode — the location and dispersion of a variable, with confidence intervals, in one table
  • Histograms, dot plots, box plots (skeletal, Tukey outlier, quantile), CDF plots and Q-Q plots with Lilliefors bands — see the shape of the distribution, and any outliers, before choosing a test
  • Shapiro-Wilk, Anderson-Darling and Kolmogorov-Smirnov normality tests — a formal check on the assumption behind a t-test or ANOVA, alongside the Q-Q plot
  • Correlation — Pearson r, Spearman rs and Kendall τ for every pair of variables, each with a confidence interval and test, and colour-mapped matrices to see the relationships
  • PCA and common factor analysis — reduce many correlated variables to a few components or factors, with Gabriel and Gower-Hand biplots and 12 orthogonal and oblique rotation methods
