I’m reaching out for ideas to improve performance issues related to quasi-complete separation encountered in about 1% of my datasets. The majority of the datasets work fine, but this small subset poses a challenge. Model Overview: Standard logistic regression, utilizing QR decomposition for ortho…

In this example, the model “knows” with very high precision what value the linear predictor should take when the covariate is -0.5, and also “knows” that the slope should be large and positive, but is very uncertain about just how large the slope should be. You can see intuitively why this would in…
