[proFit-list] Calculation of errors in fits

[pro Fit Support]

Dear Saskia

For a description of that topic, see page 115 (bottom) and 116 (top) of the manual (http://www.quansoft.com/manual/proFit_61_Handbook.pdf)

In short, the errors are in that case only derived from the covariance matrix and chi-squared. In addition, the manual says: "If you need to work with the covariance matrix, and in general for any serious statistical analysis of a fit, you must define errors for your data points!"

Best regards

Kurt Sutter
