WebThe left side of this equation is the PDF of the random variable $T$, while the right hand side gives us a formula in terms of the PDF of $T^2$, which has an F-distribution. Using that formula produces the PDF of a t-distribution with $n-1$ degrees of freedom. http://www.stat.yale.edu/~pollard/Courses/241.fall97/Normal.pdf
