Witryna22 lip 2024 · One of my professors once told me that it is possible to use "data flags" so to create dummies that are equal to 1 when the value is NA and zero otherwise. I would create those flags for every variable with NAs. And then I set the NAs to zero, afterwards I can just include the flags in the regression. Thats what I was told if I remeber ... WitrynaLinear regression was the original form that statisticians studied, and it is the easiest type of model to fit and interpret.
