Webb27 mars 2024 · We fit a mixed-effects binomial logistic regression model with a random intercept at the station level, using the melogit command in Stata 17 (StataCorp, 2024). We account for similarity within neighborhoods utilizing the clustered variance structures. Given we have a binary outcome y ij {0, 1} observed on week i, with i = 1,2,. . ., WebbIn my experience, many users of Linear Mixed Effect (LME) models tend to assume that the random effects only influence the intercept, and not the slopes, of the model.
