I am new here. The proc lifereg used to produce a model fit statistic (loglikelihood) without any of the covariates along the usual one with covariates. This is useful to compute a likelihood ratio or a pseudo r-squares. It seems I cannot find this now with newer version of SAS/ETS. Is there a solution for this? I cannot run the model with no covariates as I do not know what missing observations to exclude to have a match between the two runs (with and without covariates). Thank you in advance for any help.
