WebThe 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. WebThe problem statement also suggests the probability distribution to be geometric. The probability of success is given by the geometric distribution formula: P ( X = x) = p × q x − 1. Where −. p = 30 % = 0.3. x = 5 = the number of failures before a success. Therefore, the required probability:
