WebA continuous random variable \(X\) follows a gamma distribution with parameters \(\theta>0\) and \(\alpha>0\) if its probability density function is: ... The gamma p.d.f. reaffirms that the exponential distribution is just a special case of the gamma distribution. That is, when you put \(\alpha=1\) into the gamma p.d.f., you get the exponential ...
