Binary and multinomial logistic regression
WebThe logistic regression model is an example of a broad class of models known as generalized linear models (GLM). For example, GLMs also include linear regression, ANOVA, poisson regression, etc. Random Component – refers to the probability distribution of the response variable (Y); e.g. binomial distribution for Y in the binary logistic ... WebMultinomial logistic regression is for modeling nominal outcome variables, in which the log odds of the outcomes are modeled as a linear combination of the predictor variables. …
