family: Family Objects for Models

Webfamily is a generic function with methods for classes "glm" and "lm" (the latter returning gaussian () ). The quasibinomial and quasipoisson families differ from the binomial and poisson families only in that the dispersion parameter is not fixed at one, so they can “model” over-dispersion. WebThe generic accessor functions coefficients, effects, fitted.values and residuals can be used to extract various useful features of the value returned by glm. weights extracts a vector of weights, one for each case in the fit (after subsetting and na.action). An object of class "glm" is a list containing at least the following components: Weblibrary(statmod) # Needed to use tweedie family object ### Generate some fictitious data test.data <- rgamma(n=200, scale=1, shape=1) ### Fit a Tweedie glm and find the AIC m1 <- glm( test.data~1, family=tweedie(link.power=0, var.power=2) ) ### A Tweedie glm with p=2 is equivalent to a gamma glm: m2 <- glm( test.data~1, family=Gamma(link=log)) full form of ovm
