NettetThe term "generalized" linear model (GLIM or GLM) refers to a larger class of models popularized by McCullagh and Nelder (1982, 2nd edition 1989). In these models, the response variable y i is assumed to follow an exponential family distribution with mean μ i, which is assumed to be some (often nonlinear) function of x i T β. Nettetmdl = fitglm (tbl) returns a generalized linear model fit to variables in the table or dataset array tbl.
