Like linear models (lm()s), glm()s have formulas and data as inputs, but also have a family input. Generalized Linear Model Syntax. The Gaussian family is how R refers to the normal distribution and is the default for a glm(). Similarity to Linear Models.

TīmeklisIn 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 ... TīmeklisI have to make a nonlinear regression of these data, but I don't want to fit it to a quadratic model; instead, I wanna fit it to the equation below (an alternative to the Mitscherlich equation): Y = a − b × exp ( − c x) Y is dry weight. a is a fitted parameter representing the maximum biomass. b is a fitted parameter representing the ...
