WebIn R, a family specifies the variance and link functions which are used in the model fit. As an example the “poisson” family uses the “log” link function and “ μ μ ” as the variance function. A GLM model is defined by both the formula and the family. GLM models can also be used to fit data in which the variance is proportional to ... WebGeneralized Additive Mixed Models Description.
