Hello,

I try to fit linear or exponential functions to some data. The fitting
procedure returns some statistics, but not the R².

Can I calculate the R² (Bestimmtheitsmaß) from these values somehow in
order to be able to compare the quality of my fits? If not, is there
another easy way to do this?

Thank you,

Stepahn
