Lecture 2 Introduction to GLM’s
Generalized additive models in R GAMs in R are a nonparametric extension of GLMs, used often for the case when you have no a priori reason for choosing a particular response function (such as linear, quadratic, etc.) and want the data to 'speak for themselves'.... In R this is done via a glm with family=binomial, with the link function either taken as the default (link="logit") or the user-specified 'complementary log-log' (link="cloglog"). Crawley suggests the choice of the link function should be determined by trying them both and taking the fit of lowest model deviance.

And to emphasize the GLM approach, what is most important (if you're fitting a linear regression) is that the mean is XB and the variance is constant (i.e., that your assumptions about the first and second moments are correct)....
Each set of commands can be copy-pasted directly into R. Example datasets can be copy-pasted into .txt files from Examples of Analysis of Variance and Covariance (Doncaster & Davey 2007). For a given design and dataset in the format of the linked example, the commands will work for any number of factor levels and observations per level.

Generalized Linear Model (GLM) — H2O 3.22.1.1 documentation
Poisson regression is a type of a GLM model where the random component is specified by the Poisson distribution of the response variable which is a count. Before we look at the Poisson regression model, let’s quickly review the Poisson distribution. how to become obsessed with studying Poisson regression is a type of a GLM model where the random component is specified by the Poisson distribution of the response variable which is a count.

  • Introduction. Glmnet is a package that fits a generalized linear model via penalized maximum likelihood. The regularization path is computed for the lasso or elasticnet penalty at a grid of values for the regularization parameter lambda.
  • Is a mixed model right for your needs? A mixed model is similar in many ways to a linear model. It estimates the effects of one or more explanatory variables on a response variable. The output of a mixed model will give you a list of explanatory values, estimates and confidence intervals of their effect sizes, p-values for each effect, and at least one measure of how well the model fits.
