%%
% The mode of the Student's _t_ distribution is at _x_ = 0. This example
% shows that the value of the function at the mode is an increasing
% function of the degrees of freedom.
tpdf(0,1:6)

%%
% The _t_ distribution converges to the standard normal distribution as the
% degrees of freedom approaches infinity. How good is the approximation for
% $\nu$ equal to 30?
difference = tpdf(-2.5:2.5,30)-normpdf(-2.5:2.5)
