Hello, is LazStats still actively maintained by mr. Miller?
Does not look like that, even the link in the previous post is not working any more. I finally could download the Windows (*) sources from
https://openstat.info/LazStatsMain.htm. Compilation did work after some changes (replaced GraphFrm.AutoScale by .AutoScaled due to a naming conflict), but at runtime I get a grid error that "FixedRows can't be > RowCount." which can be resolved by setting "DictionaryFrm.DictGrid.RowCount := DictionaryFrm.DictGrid.FixedRows;" in TOS3MainFrm.FormShow, unit MainUnit.
Is there any Lazarus software dealing specifically with DOE (Design Of Experiments)?
I don't think so. Isn't it true that DOE in the end comes down to linear regression? In this case you could try the fitting routins built into TAChart. Or try DMath available via Online Package Manager, or JediMath (
https://sourceforge.net/projects/jedimath/). Some forms require some redesign.
(*) The windows unit is used by some units. In all of them it can be removed. There is a variable named RichEdit in the code but this already has been replaced by a TMemo.
