Office XP compatible

Improved license system and installer. Existing users upgrading to version 1.60 or later must request a license key (see below).

Added linearity protocol. No documentation is included for this procedure as yet, but an example called "Linearity.xls" is included in the "Analyse-it\System\Examples" folder. If you have any questions please contact us.

Changed linear regression prediction intervals to use t-distribution instead of F-distribution. Warning: the new t-distribution implementation yields narrower prediction intervals compared with the F-distribution.

Added "no intercept in model" to linear regression allowing fitted regression line to be forced through 0 (a.k.a. zero forcing).

(1 Feb 1999)

Made Analyse-it Office/Excel 2000 compliant. Also fixed new problems introduced by Microsoft Office/Excel 97 service packs.

Improved linear regression algorithm to produce more accurate results when dependant variables are highly co-linear (now results are more accurate than Minitab!)

Version 1.28
(27 Apr 1998)

Modified precision plot, and fixed bug in the %difference plot of bias plots.

Modified ROC analysis to automatically decide whether higher or lower diagnostic results indicate normal or abnormal.

Version 1.25
