Hello to al,
Do someone know how to get the CDF And Quantile Functions for a Student distribution.
I already looked here:

Wouldn't combining those functions, using the t distribution, provide what you want?

The CDF and QUANTILE functions support the Student t distribution. The doc shows "T" as a valid distribution.
data Want;
df = 11;
do x = -3 to 3 by 0.1;
pdf = pdf("T", x, df);
cdf = cdf("T", x, df);
q = quantile("T", cdf, df);
output;
end;
run;
title "PDF and CDF for t(df=11) distribution";
proc sgplot data=want;
series x=x y=pdf;
series x=x y=cdf;
run;
title "Quantile function for t(df=11) distribution";
proc sgplot data=want;
series x=cdf y=q;
run;
Yes absolutly, both work very well with the t distribution. Thanks so much to all.
Thank you Dr Rick W. for this very clear example.
