fitting x y data to student t-distribution

hi as the question makes fairly evident, I want to be able to fit a t-distribution to a 12 long vector of x and y data, so far i cant seem to find a way to do it

"to fit a distribution" usually means to estimate its parameters, so "to fit the t-distribution" would mean estimating its only parameter--i.e., the degrees of freedom. I doubt this is what you really want to do since you seem to have data scores x and y. If you can't do what you want with the ttest or ttest2 command, could you explain in more detail what your x and y values are, and what you want to do with them.
