%% Compute Noncentral _t_ Distribution pdf % % Copyright 2015 The MathWorks, Inc. %% % Compute the pdf of a noncentral _t_ distribution with degrees of freedom % |V = 10| and noncentrality parameter |DELTA = 1|. For comparison, also % compute the pdf of a _t_ distribution with the same degrees of freedom. x = (-5:0.1:5)'; nct = nctpdf(x,10,1); t = tpdf(x,10); %% % Plot the pdf of the noncentral _t_ distribution and the pdf of the _t_ % distribution on the same figure. plot(x,nct,'b-','LineWidth',2) hold on plot(x,t,'g--','LineWidth',2) legend('nct','t')
