Hi,

I have a set of experimental data taken which should fit into Lorentian and Gaussian equations.
I need to find the goodness of fit and other related fitting parameters.I have 500 data in each set.

I need to know how this can be done.Pls send any related articles/project reports.
 

here is a very powerful tool for non-linear regression analysis:

you can download a free trial version, 500 data is not a problem at all.
