Hi,
could you please tell me how to get the correlation coefficients and the status of minuit
when using TVirtualFitter
thanks

Hi
there is no method in TVirtualFitter to get the correlation coefficient directly.
You can get however via the covariance matrix elements:
double corr_ij = virtualFitter->GetCovarianceMatrix(i,j)/
sqrt( virtualFitter->GetCovarianceMatrix(i,i) * virtualFitter->GetCovarianceMatrix(j,j) );
The status of Minuit is returned as an integer word in the TVirtualFitter::ExecuteCommand
