We are receiving a lot of questions about relevant analyses in the Analyse-it Method Validation edition to help in evaluating new diagnostic tests in the fight against COVID-19. Below are some quick links that will help, but contact us if you have questions - we are working as normal.

We’ve been busy over the last few months adding
various new features and improvements to Analyse-it.
There are always many
changes behind the scenes, which aren’t really news-worthy, but seek to make
Analyse-it compatible with the latest changes to Microsoft Excel and Windows. Microsoft
have recently embraced a more aggressive continuous-release deployment model
with Office and Excel, and these releases have caused quite a few headaches for
developers, notably with the multi-monitor high DPI support.
For these reasons we advise you have active maintenance so you get these
updates as they are released – if not we recommend you renew maintenance on your license to get the latest updates and ensure compatibility
with the often fast-paced releases.
Starting with version 5.20 we introduced a
new feature so you can set the scale (minimum, maximum and units) for a
variable that will then be used, where possible, to set the scaling for chart
axes. Normally Analyse-it will choose excellent axis scaling, but sometimes you
know better and want a specific minimum, maximum, or units. Previously you would
have to set the scale manually on the charts output from the analysis, and any
changes would be lost on recalculate. Now you can control the scaling, see Setting the minimum, maximum and units of a variable
With version 5.30 we focussed on improving
the Fit model analysis, with the addition of weighted regression and the
Durbin-Watson statistic for testing autocorrelation in the residuals. For more
information see the updated documentation, Linear fit and Residuals - independence.
Finally, in version 5.40 we added equivalence
tests. Unlike the usual equality of means hypothesis test which tests for a difference, an equivalence of means hypothesis
test tests if two population means are equivalent, that is, practically the
same. We’ve added the equivalence tests to Distribution, Compare Groups and
Compare Pair analyses. You can read more about these changes at Distribution - Parameter equivalence hypothesis test, Compare groups – equivalence of means hypothesis test,
and Compare pairs – equivalence of means hypothesis test
If you have active maintenance you can download and install the update now, see updating the software. If maintenance on your license has expired you can renew it to get this update and forthcoming updates, see renew maintenance.
Update 19-Sep-2019: Unfortunately this continues to be an issue for some users and unfortunately there is currently no solution from Microsoft except to suggest the use of compatibility mode as detailed below. We have requested this be fixed, so please up-vote it at
Update 27-Jun-2018: Although we have a fix for this issue on an internal build, it appears that Microsoft Office version 1807 (which is currently only available on the Office Insider track) fixes this issue. The missing user-interface problem was caused by a bug in Microsoft Office 1805/1806 updates. We will release our fix shortly, but the 1807 version update will also become available to everyone over the next month or so. If you want to get it immediately see .
Microsoft officially released a couple of days ago, and Analyse-it version 4.20 now adds support for Excel 2016.
Over the next few weeks we will tweak the Analyse-it user interface so it matches the new Office 2016 user interface styles. Line styles on the plots in Excel 2016 now also appear a lot thicker, due to anti-aliasing (smoothing), so we will decide whether to address that in a future update – let us know what you think.
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?
Sorry, it’s a trick question, because (visually) there is no difference. The difference is how the values are stored by Microsoft Excel. The value 57 in the cell on second row is actually stored as a text string, not a number.
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 cells on the report were being lost on refresh.
As an example, suppose you have used Analyse-it linear regression to calculate the linear relationship between installation cost and the number of employees required, distance to the site, and the cost of machine being installed. Analyse-it would calculate the effect of each variable on the final cost, technically known as regression coefficients, which you can then use to predict installation costs for jobs in future.
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:
Chart size is only limited by the page size your printer supports.
