# How can I estimate the degrees of freedom for a Student's T distribution?

I am doing research estimating the value at risk for non-normally distributed assets. I need help in the process of estimating the parameters of Student's t distribution and which method to use. I would highly appreciate any assistance in this issue.

Should this question perhaps be migrated to stats.SE? –  Tal Fishman Aug 8 '11 at 3:22
