  • Analyse-it 6.22 released: Install without administrator rights

    Until now, installing Analyse-it needed administrator rights. On many laboratory and company computers that meant asking IT to install it for you, and asking again for every update. From version 6.22, you don’t need to.

  • 2023

  • A New Year. A New Edition

    Last year was a productive year for Analyse-it, with the addition of survival analysis functions Kaplan-Meier survival curves and Cox's proportional hazards regression .

  • Calculating the detection limit for a SARS-CoV-2 RT-PCR assay using Analyse-it

    Recent improvements to the Analyse-it Method Validation edition, in version 5.50 and later, include the addition of probit regression. Probit regression is useful when establishing the detection limit (LoD) for an RT-qPCR assay.

  • Calculating PPA/NPA agreement measures using Analyse-it

    Following our last blog post, today, we will show how to calculate binary agreement using the Analyse-it Method Validation edition. The CLSI EP12: User Protocol for Evaluation of Qualitative Test Performance protocol is a useful companion resource for laboratories and diagnostic…

  • Diagnostic accuracy (sensitivity/specificity) versus agreement (PPA/NPA) statistics

    Due to COVID-19, there is currently a lot of interest surrounding the sensitivity and specificity of a diagnostic test. These terms relate to the accuracy of a test in diagnosing an illness or condition.

  • Establishing the diagnostic accuracy (sensitivity/specificity) of a test using Analyse-it

    It is important in diagnostic accuracy studies that the true clinical state of the patient is known. For example, in developing a SARS-CoV-2 anti-body test, for the positive subgroup, you might enlist subjects who had a positive SARS-CoV-2 PCR test and clinically confirmed…

  • Why the diagnostic test 'accuracy' statistic is useless

    In our last post, we mentioned that the 'accuracy' statistic, also known as the probability of a correct result, was a useless measure for diagnostic test performance. Today we'll explain why.

  • Sensitivity/Specificity and The Importance of Predictive Values for a diagnostic test

    There’s currently a lot of press attention surrounding the finger-prick antibody IgG/IgM strip test to detect if a person has had COVID-19. Here in the UK companies are buying them to test their staff, and some in the media are asking why the government hasn’t made millions of…

  • Training and consultancy for Analyse-it

    Our focus at Analyse-it has always been on the development and improvement of our software. While we provide extensive help, tutorials, and technical support for Analyse-it, one area we do not cover is training and consultancy.

  • Analyse-it 5.10 released: Save and re-apply filters

    It’s been a long-requested feature, and today we’re happy to announce that Analyse-it version 5.10 now includes the ability to save the dataset filter with an analysis and re-apply it on recalculation.

  • Microsoft Windows, Office 2016, multiple monitor DPI awareness - and Analyse-it's missing user interface

  • 2017

  • Analyse-it 4.90 released: Prediction intervals, EP14-A3 and EP30-A

    Prediction intervals on Deming regression are a major new feature in the Analyse-it Method Validation Edition version 4.90, just released.

  • Parameter estimation

    Often we collect a sample of data not to make statements about that particular sample but to generalize our statements to say something about the population.

  • Analyse-it 4.80 in-depth: The revamped documentation

    As we mentioned last week in the post announcing Analyse-it 4.80, in this release we took the opportunity to revamp the documentation.

  • Analyse-it 4.80 released: ANOVA, ANCOVA and revamped documentation

    Last week we released version 4.80 of Analyse-it. The new release includes multi-way ANOVA, ANCOVA, and Cronbach’s Alpha in the Standard edition, and since every licence includes the Standard edition, these features are available to all users.

  • 2014

  • Analyse-it 3.80 released: Principal Component Analysis (PCA)

    Today we released version 3.80 of the Analyse-it Standard edition. The new release includes Principal Component Analysis (PCA), an extension to the multivariate analysis already available in Analyse-it.

  • Quantile and percentile formulas: why Excel, R and SAS give different answers

    What is a sample quantile or percentile? Take the 0.25 quantile (also known as the 25th percentile, or 1st quartile) -- it defines the value (let’s call it x) for a random variable, such that the probability that a random observation of the variable is less than x is 0.25 (25%…

  • Analyse-it 3.10 now includes a statistical reference guide

    Yesterday we improved the help in the Analyse-it Standard Edition and added a statistical reference guide. The guide tells you about the statistical procedures in Analyse-it, with help on using and understanding the plots and statistics.

  • 2008

  • Numbers stored as text in Excel, and why SUM ignores them

    In clearly titling this blog post, we’ve probably already revealed the answer, but... Can you spot the difference between the two rows of values in the Excel spreadsheet shown below?

  • Analyse-it speeds Method Validation at National Laboratory

    Today we’re delighted to publish the second case study into the use of Analyse-it. The case study features a national clinical laboratory in the USA that offers more than 2,000 tests and combinations to major commercial and government laboratories.

  • Normal quantile plots and Q-Q plots: how to read them

    In a previous post, Testing the assumption of Normality, we explained the tests provided in Analyse-it to determine if a sample has normal distribution. In that post, we mentioned that although hypothesis tests are useful you should not solely rely on them.

  • Using INDIRECT to refer to cells on Analyse-it analysis reports

    A customer contacted us last week to ask how to refer to cells on an Analyse-it report worksheet, from a formula on another worksheet. The customer often used Analyse-it's refresh feature, to repeat the statistical analysis and update the statistics, and direct references to…

  • Analyse-it Cuts Project Time in Half at Swiss Lab

    Today we’re delighted to publish the first case study into the use of Analyse-it. Marco Balerna Ph.D., a Clinical Chemist at the EOC (Ente Ospedaliero Cantonale) in Switzerland, used Analyse-it when replacing the clinical chemistry and immunological analysers in EOC’s…

  • How to print a chart on a full page in Excel

    Although the charts in Analyse-it are large so they’re easy to read when printed, sometimes you need to print a chart to fill the full page. You can do so easily, without resizing the chart, in just a few steps:

  • Identifying what, when and who analysed it

    Identifying what was analysed, when, and by who, is the first step in understanding any Analyse-it report. The top rows of each Analyse-it report provide you with this information.

  • Unfiled reports, Collate, and Analyse-it 3

    In May this year, we surveyed users of the Analyse-it Method Evaluation edition to gain insight into how we can improve Analyse-it in future. Thank you to all those who responded.

  • Testing the assumption of normality

    The most used distribution in statistical analysis is the normal distribution. Sometimes called the Gaussian distribution, after Carl Friedrich Gauss, the normal distribution is the basis of much parametric statistical analysis.

  • The Analyse-it "Dataset" concept

    For new and occasional Analyse-it users, datasets can sometimes seem confusing. Today we’ll explain why we devised the 'dataset' concept, a concept now copied by some other Excel add-ins.

  • Handbook of Parametric & Non-parametric Statistical procedures

    A few readers have e-mailed to ask for more information about the book by David J. Sheskin we alluded to in the comment reply re: the Statistical test advisor, last week.

  • How to get help using Analyse-it

    Most of you know where to find the help and examples provided with Analyse-it, but if not, today we’d like to explain what’s available. If you're stuck we're always happy to help, and usually respond within a few hours, but it's always faster for you to check if the help answers…
