It is well known that a random variable being Gamma distributed with integer shape parameter k$k$ is equivalent to the sum of the squares of k$k$ normally distributed random variables.

But what can I say about a gamma distributed random variable with non-integer k$k$? Is there any other interpretation other than the Gamma distribution at all?
