Thanks. I just refactored the unit to my current standard. But I cannot find the position in the code, there is no comment "get independent variable columns" in my copy, only a "get dependent variaible columns". Except for this difference, a few lines later there are lines which seem to match. Just to make sure: What is the name of the procedure? TLSMregForm.ComputeBtnClick? Near the beginning after the bunch of SetLength instructions?
Did you happen to find the help file related to this form? The pdf usually contains a tested example of OpenStat which allows me to check the routine.
If there is not help file and no demo can you submit a sample file with the expected results?
it's in procedure TLSMregForm.ComputeBtnClick(Sender: TObject);
yeah, comment was added by me...
you can use the file (9_23_results.tab), link here:
