Good day everyone,

I want to assess the error when fitting a Gram-Charlier
CDF to some data 'ws', that is, I want to calculate:

     Err = |ecdf(ws) - GCh_ser(ws)|

The problem is, I cannot get the F(x) values from the

'Summary(ecdf())' returns some of the x-axis values,
but how do you get the F(x) values?

Thank you for any help you can provide.
