MedCalc 22.023

Corrected a problem in the calculation of Nagelkerke's R2 in Logistic and Probit regression, in case of a large null model ?2 Log Likelihood.
Corrected a problem that caused failure of saving very large Excel files (*.xlsx).
When bootstrapping takes a long time, a dialog box is displayed with the estimated time left, and a button to interrupt the procedure.
New: scientific, mathematical and system Constants.
New functions: Random, Pow10, CountIf, SumIf, BOXCOX Box-Cox transformation, and BOXCOXINV inverse of the Box-Cox transformation.
Improved speed of several statistical procedures.

In Frequency tables (Chi-squared test) and Fisher's exact test, moved the option to show all percentages from the results window to the dialog box. This fixes a problem with copying-pasting results to other programs.
Fixed a bug in the Categorize function, which could cause the function to always return the default value.
Fixed a problem with multiple monitors.

Version 22 introduces a new file format. The new format is faster and lighter. Important: files saved in MedCalc version 21 cannot be read by previous MedCalc versions. Files saved in all previous MedCalc versions can be read by this version; but when saved, the new file format is used.
New: Scripts
New spreadsheet functions EVAL, FREQUENCY, VFREQUENCY, DEVSQ, VDEVSQ, INTERCEPT, VINTERCEPT, STEYX, VSTEYX, TESTNORM and VTESTNORM.
Redefined the CELL function.
Fixed a bug in Case control matching when saving the matched data to a new file.
In Diagnostic test (2x2 table): when predictive value is 0 or 100%, a Clopper-Pearson confidence interval is reported.
New operators ! (Not), && (And), || (Or)
The operator != can be used as an alternative to the <> (Not equal) comparison operator. E.g. 5!=1 is true.
