A gamma distribution with shape parameter α = v /2 and rate parameter β = 1/2 is a chi-squared distribution with ν degrees of freedom. boots chemist handforthNettetA generalized linear regression model has generalized characteristics of a linear regression model. The response variable follows a normal, binomial, Poisson, gamma, or inverse Gaussian distribution with parameters including the mean response μ. A link function f defines the relationship between μ and the linear combination of predictors. hatfield 12 gauge pump shotgun
