Fitting gamma distribution excel
WebGAMMA.INV (probability,alpha,beta) The GAMMA.INV function syntax has the following arguments: Probability Required. The probability associated with the gamma distribution. Alpha Required. A parameter to the distribution. Beta Required. A parameter to the distribution. If beta = 1, GAMMA.INV returns the standard gamma distribution. Webfrom which it follows that. and so. or. Since. it follows that. and so. which gives us the estimates for μ and σ based on the method of moments. Reference: Genos, B. F. (2009) Parameter estimation for the Lognormal distribution.
