polynomial fit quality: estimators for coefficients

[nimic]

Hello

When running a polynomial fit on some data, I want to know, how 'good' my fit parameters are. Some evaluation programs (Minitab, Excel) offer an estimator i.e. some sort of sigma on the a, b and c coefficients. Is there a similar functionality in DIAdem?

Thank you for your assistance.

Hi Michael,

There is a "coefficient of determination" which the DIAdem (polynomial) Approximation function puts in the variable "ApprPrecision".
