WebFit Gamma Distribution to Data Generate a sample of 100 gamma random numbers with shape 3 and scale 5. x = gamrnd (3,5,100,1); Fit a gamma distribution to data using fitdist. pd = fitdist (x, 'gamma') pd = GammaDistribution Gamma distribution a = 2.7783 [2.1374, 3.61137] b = 5.73438 [4.30198, 7.64372] fitdist returns a GammaDistribution object. WebApr 20, 2024 · One distribution enables fitting many other distributions. Setting p = 0 gives a normal distribution, p = 1 is Poisson, p = 2 gives a gamma distribution and p = 3 yields an inverse Gaussian. ...
