Mlogit unknown reference level
Web14 apr. 2024 · To run a multinomial logistic regression, you'll use the command -mlogit-. You can see the code below that the syntax for the command is mlogit, followed by the outcome variable and your covariates, then a comma, and then base (#). In this example I have a 4-level variable, hypertension (htn). I want the reference category, or the base … WebIt's not a question of mlogit in particular, it's a question of how multinomial logistic regression works. If your dependent variable has 3 levels, you will have 2 intercepts. And you have …
