Gamma glm in python

Webmath.gamma (Number) = (Number – 1)! It means the gamma function subtracts one from the Given number, and then it finds the factorial. For example, math.gamma (6) = 5!. … Weballelizable. There is currently no R package that implements a parallelizable GLM for Gamma, so the current work fills this gap. Table 1 is a summary of existing R packages for GLM, to the authors’ best knowledge. In particular, we provide an e cient, parallelizable package that can fit a GLM model with EN regularization for the Gamma family.
