Hi all, I currently have this program which is supposed to simulate a gambling strategy (educational purposes; this is not a winning strategy by any means).  My program is not quite working because when the 2nd iteration of k begins, the InHand variable continues to accumulate from the final value of when k = 1.  Essentially, I need the InHand to go back to starting at 0 when a new iteration of k begins.  Basically, I just want to repeat everything in the 'i' loop 10,000 times Does anyone have an idea of a modification I can make to fix this? data gamble; do k = 1 to 10000; do i = 1 to 100000 until (Strategy = "STOP"); Win = RAND('BINOMIAL',0.476,1); if Win = 1 then Payoff = 5; else if Win = 0 then Payoff = -5; InHand + Payoff; if InHand >= 45 then Strategy = "STOP"; else if InHand <= -50 then Strategy = "STOP"; else Strategy = "CONTINUE"; if InHand = 45 then Result = "WIN "; else Result = "LOSS"; end; output; output; end; run; Thank you in advance! ...

Hello everyone, I'm trying to learn the best way to get both predicted values and confidence intervals for observations in a test dataset when you are using a model based on a separate training dataset.  Better yet, what if I'm just working with one dataset, but some of the observations are missing the dependent variable.  How can I get the predicted value/confidence interval for these assuming I have all of the predictor variables present? In my coursework, I've learned to use Proc Score which does give you the predicted values, but it doesn't get you the confidence intervals.  Is there a way to get this in SAS? Thanks in advance to anyone that can help! ... View more
