WebMay 28, 2024 · Some of the assumptions of Logistic Regression are as follows: 1. It assumes that there is minimal or no multicollinearity among the independent variables i.e, predictors are not correlated. 2. There should be a linear relationship between the logit of the outcome and each predictor variable. WebFeb 19, 2024 · What is the intuition behind `weights` in glm in R? This question was migrated from Stack Overflow because it can be answered on Cross Validated. Migrated last month. To perform generalized linear regression using R, there is an option in glm where i can put weight to each of the observation by weights . Now I want to know what does it actually do?
