Web1 jan. 2024 · With the logistic regression model, heteroscedasticity is automatically assumed to exist. The conditional distribution of Y given X = x is assumed to be Bernoulli with parameter π ( x), a probability. The variance of this distribution is π ( x) × ( 1 − π ( x)), a nonconstant function of x. Likewise, you do not need to worry about normality. WebThe robust variance estimator goes by many names: Huber/White/sandwich are typically used in the context of robustness against heteroskedasticity.
