the model fails to converge after more than 3 hours ( I went home so don't know how long it took)
> bigglm (formula = resp ~ relage+I(relage^2)+termfac+ri , + data = a, family = binomial(link='logit')); Large data regression model: bigglm(formula = resp ~ relage + I(relage^2) + termfac + ri, data = a, family = binomial(link = "logit")) Sample size = 12758187 failed to converge after 8 iterations Warning message: In bigglm.function(formula = resp ~ relage + I(relage^2) + termfac + : ran out of iterations and failed to converge SAS converges NOTE: PROC LOGISTIC is modeling the probability that resp='1'. NOTE: Convergence criterion (GCONV=1E-8) satisfied. NOTE: There were 12758187 observations read from the data set SRVRUSER.COMMIT. NOTE: The data set WORK.OUT3 has 11 observations and 15 variables. NOTE: PROCEDURE LOGISTIC used (Total process time): real time 2:25.42 cpu time 1:16.79 I did not see a trace argument in bigglm. is there another way to see what is happening?
