Suppose X is a gamma variate with E(x) = 3 and var(X ) = .7 Find the parameters
α and λ of the gamma distribution.
A random variable X which has the gamma distribution with a shape parameter "\\alpha" and a rate parameter "\\lambda" (i.e. "X\\sim \\Gamma (\\alpha ,\\lambda )" ) has the following mean and variance:
Hence
"\\alpha=3\\lambda=\\dfrac{90}{7}\\approx 12.8571"
