Sas stopped because of infinite likelihood

Webb17 aug. 2024 · The algorithm is on track to maximize the likelihood, but it has to stop when regression coefficients become numerically too large for the software to handle. Separation can also arise as a consequence of the joint effects of continuous covariates, even if no covariate achieves separation alone. Webb• The method=REML option calls the restricted maximum likelihood estimator for the model and is a default method. REML is selected because it typically provides less …
