Hi,
I'm having a similar issue with a dataset with 750,000 observations. I'm only imputing 6 variables, and I'm using REG for four of those. However, I wanted to use REGPMM for two attendance rate (percentage) variables because using REG results in numbers over 100. I've tried using the MAX option before but that didn't work.
Is there anyway to increase the efficiency of this operation? If not, is there a way to estimate the length of time that is needed? I've tried gradually increasing the number of observations, but the effect on computation time doesn't seem linear.
Thanks,
Bill
