Web# Testing exponentiality on a simulated random sample from the exponential distribution x <- rexp(20) exp_test(x) gamma_fit Fitting the Gamma distribution to data Description Fits a Gamma distribution to a random sample of positive real numbers using Villasenor and Gonzalez-Estrada (2015) parameter estimators. Usage gamma_fit(x) WebThe probability density function for expon is: f ( x) = exp. . ( − x) for x ≥ 0. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters. Specifically, expon.pdf (x, loc, scale) is identically equivalent to expon.pdf (y) / scale with y = (x - loc ...
