Hello there, I am having a very similar problem. Note: proc logistics works fine, it is when I run the bootstrapped weights that I run into a problem. What does the INEST option mean? what can be the solution for me? Thank you for your help. Razan Below is my syntax: Proc surveylogistic data=boot.merged_1 varmethod=BRR ; class ADHR (ref=first) DHH_SEX (ref=first) year(ref=first) agegrp (ref=first) edu_lv (ref=first) ; model adhr = DHH_SEX year agegrp edu_lv / RIDGING=NONE ; repweights bsw1 - bsw500 ; weight fwgt ; run; NOTE: PROC SURVEYLOGISTIC is modeling the probability that adhr=1. NOTE: Convergence criterion (GCONV=1E-8) satisfied. WARNING: The linesearch technique has failed to improve the loglikelihood. You may want to increase the maximum number of step halvings (HALFMAX= option), or switch to use a ridging technique (RIDGING= option), or specify a new set of parameter estimates (INEST= option). WARNING: The SURVEYLOGISTIC procedure continues in spite of the above warning. Results shown are based on the last maximum likelihood iteration. Validity of the model fit is questionable. NOTE: PROCEDURE SURVEYLOGISTIC used (Total process time): real time 3:00.49 cpu time 2:15.08
