statistical tool/program for obtaining stiffness properties by force-deflection data

I am performing flexural testing of composite honeycomb sandwich panels as per D7250,desired deliverables(stiffness values G,U and D) are obtained as a result of statistical analysis which involves simple calculations of mean,std,COV and linear regression on force-deflection data,linearity check (via toe compensation) and hence the final calculations of these stiffness values.

can someone suggest a program/software that can perform all these statistical operations and I just need to plug in the data in the form of data(for means and force-deflection data for linear regression)? does any program/software have a feature for toe-compensation too?

A software that has a user-friendly GUI...
