Complete, not compromised

Not a subset of each technique — the full procedure, with diagnostics, plots, and multiple comparison procedures. From descriptive statistics through ANOVA, ANCOVA, regression, logistic regression, PCA, and factor analysis with 12 rotation methods.

NIST-validated accuracy

All calculations run in Analyse-it's own engine — not Excel's built-in functions, which have documented accuracy failures. Validated against the NIST Statistical Reference Datasets with IEEE 754 double-precision arithmetic throughout.

Task-based workflows, not feature menus

Analyses organised into logical workflows — describe, compare, correlate, model — so you can find what you need without hunting through menus. Build the analysis, examine the diagnostics, refine, and re-run. Results update immediately in your workbook.

Excel's built-in Analysis ToolPak handles the simplest cases — a one-way ANOVA, a basic regression, a histogram — and stops. The output is static, the diagnostics are absent, and the accuracy of some calculations is poor (documented failures against NIST reference datasets). For anything beyond the basics — multi-factor ANOVA, multiple comparisons, logistic regression, PCA, residual diagnostics — there is no built-in option. Most researchers and analysts hit this wall quickly.

Analyse-it replaces the ToolPak entirely with a professional-grade statistical package inside Excel. Descriptive statistics with normality tests, histograms, box plots, Q-Q plots, and CDF plots. Hypothesis tests including t-tests, Welch's t, Wilcoxon-Mann-Whitney, paired tests, and non-parametric alternatives. One-way, two-way, and multi-factor ANOVA and ANCOVA with nine multiple comparison procedures, interaction plots, leverage plots, and residual diagnostics. Simple, multiple, polynomial, and logistic regression with full model-building workflows. PCA with the most advanced biplot implementation in any commercial statistics package, and Factor Analysis with 12 rotation methods. Pearson, Spearman, and Kendall correlation with colour-mapped matrices. Contingency tables with Fisher exact, McNemar, and mosaic plots.

Every analysis is organised as a task-based workflow rather than a list of statistical functions. Choose the analysis type, select your data, and get a complete result — estimates, confidence intervals, assumption checks, diagnostics, and plots — in a single step. When the diagnostics suggest a problem, adjust the model and re-run. Results update immediately in the same workbook. No separate application to learn, no proprietary file format, no data import step. Share the workbook with a colleague and they see everything.

75,000 researchers, analysts, and scientists at leading universities, hospitals, and companies worldwide have relied on Analyse-it for over 30 years.

  • Model binary outcomes with logistic regression

    Binary logistic and probit regression with odds ratios, confidence intervals, AIC/BIC, term-level tests, leverage plots, and influence diagnostics. See logistic regression details.

  • Reveal structure with PCA and factor analysis

    PCA with Gabriel and Gower-Hand biplots, scree plots, correlation monoplots, and prediction. Factor Analysis with 12 orthogonal and oblique rotation methods. Cronbach's alpha for item reliability. Colour-mapped coefficient and correlation matrices. See PCA and factor analysis details.

  • Analyse categorical data

    Contingency tables with Pearson chi-square, likelihood ratio, Fisher exact test, McNemar test. Proportion tests and estimators. Odds ratios and risk ratios with confidence intervals. Mosaic plots for visualising the association structure.

  • Trust the results

    All calculations run in Analyse-it's own engine — no Excel formulas. Validated against the NIST Statistical Reference Datasets. Tested automatically after every change to the software. See the development and validation process.
