[gradsusr] what exact algorithm used in scorr

[ting lei]

Dear Grads Users,

Can any one show the exact algoritm/procedures used in the function scorr?

For example, what formula is used;  how scorr treat the missing values (
and how it know the values are the missvalues).
It is important for me because I found differences between the scorr
results and the one I calculated by myself , which can't be attributed to
numerical round-off errors.

Your help is appreciated.
Best regards,
Ting Lei
