Webbsuch as those with normally distributed outcomes are more commonly discussed in the literature than the models with non-normal outcomes. Also, even when considered, models with dichotomous outcomes (e.g., pass/fail) are more often discussed than those with polytomous outcomes (e.g., below basic, basic, proficient), the latter ones being

WebbCommonly used models in the GLM family include binary logistic regression for binary or dichotomous outcomes, Poisson regression for count outcomes, and linear regression for continuous, normally distributed outcomes. This means that GLM may be spoken of as a general family of statistical models or as specific models for specific outcome types. WebbBinary outcomes in cohort studies are commonly analyzed by applying a logistic regression model to the data to obtain odds ratios for comparing groups with different sets of characteristics. Although this is often appropriate, there may be situations in which it is more desirable to estimate a relative risk or risk ratio (RR) instead of an odds ratio (OR).
