SpletGamma Distribution in Python You can generate a gamma distributed random variable using scipy.stats module's gamma.rvs () method which takes shape parameter $a$ as its argument. When $a$ is an integer, gamma reduces to the Erlang distribution, and when $a=1$ to the exponential distribution. Splet01. dec. 2024 · Here is some gamma regression data N = 100 x = np.random.normal (size = N) true_beta = np.array ( [0.3]) eta = 0.8 + x*true_beta mu = np.exp (eta) shape = 10 #parameterize gamma in terms of shaope and scale y = gamma (a=shape, scale=mu/shape).rvs () Now, I will fit the gamma regression to this data

The benefit of not defining loggamma as log ( Γ ( z)) is that the latter function has a complicated branch cut structure whereas loggamma is analytic except for on the negative real axis.
