WebNegative binomial regression analysis. In the Mplus syntax below, we specify that the variables to be used in the negative binomial regression are daysabs, math, p2, p3, which will make prog=1 the reference group. We also specify that daysabs is a count variable, and we include (nb) to indicate that we want a negative binomial regression. (By ... Web6.1 - Introduction to GLMs. As we introduce the class of models known as the generalized linear model, we should clear up some potential misunderstandings about terminology.
