I don't think this is logistic any more. It sounds like a generalized linear model, and you would need to know the distribution of the dependent variable errors. ... View more

The only way I can get numbers like R-squared is to output the residual values to a data set and then calculate R-squared from those. ... View more

You can also output the standard error of the residual, and from that compute the standardized residual. ... View more

I don't think you can run a Cluster Analysis of zip code. Simply doesn't make any sense to use a categorical variable in Cluster Analysis. Can you state in words what results you are looking for from this zip code information, instead of stating "Cluster Analysis" is what you are looking for? Message was edited by: Paige ... View more

For my purposes, the answer is NO, because the incoming strings aren't truly arbitrary. However, I could see situations where the answer would be YES. ... View more

Identify legal > characters and substitute a legal character (such as > '_') for the others. Your solution still requires me to go through the string character by character, and translate as needed. Which is what I was hoping to avoid. Actually, my idea of using TRANSLATE is a whole lot easier for me to program than looping through each character. I was hoping there was a SAS function that would do the job for me. ... View more

I am not aware of a way to do this with PROC SHEWHART commands. It is probably possible using ANNOTATE graphics. ... View more

I think you have figured out the basic procedure. First, run PROC SHEWHART on all data, tell it to create no charts, and save the limits to a file. Second, run PROC SHEWHART on just the data you want to chart, tell it to use the limits calculated above. ... View more

All of this might make sense in some situations, but the original request was to compute a variance, not compare means. Which is why I keep asking for clarification on exactly what the user wants.
