Linear regression nan

Nettet8. apr. 2024 · 1 Answer. R/GLM and statsmodels.GLM have different ways of handling "perfect separation" (which is what is happening when fitted probabilities are 0 or 1). In Statsmodels, a fitted probability of 0 or 1 creates Inf values on the logit scale, which propagates through all the other calculations, generally giving NaN values for everything. NettetEstimators that handle NaN values¶ Some estimators are designed to handle NaN values without preprocessing. Below is the list of these estimators, classified by type (cluster, …

This can be caused by the presence of missing data, which your model cannot handle, or by the presence of zeros in the data that can generate NA/NaN/Inf inside other functions. The solution is to remove missing data and/or zeros. christ hospital outpatient therapy
