Hi, How can I perform a Q-Q Plot versus a Student-t distribution with let's say 15 degrees of freedom instead of normal distribution in Matlab? Thank you. Jacqueline

From the documentation of the qqplot:
" qqplot(X,PD) makes an empirical quantile-quantile plot of the quantiles of the data in the vector X versus the quantiles of the distribution specified by PD, a ProbDist object of the ProbDistUnivParam class or ProbDistUnivKernel class."
To create PD: probdistunivparam
