MLThe following error messages appeared in log window after running of a module in that EXP function was used in IML.
ERROR: (execution) Invalid argument to function.
count : number of occurrences is 607
operation : EXP at line 3007 column 13
operands : _TEM1013
_TEM1013 1999 rows 1 col (numeric)
Dose the error was caused by the too large argument of EXP? How to deal with that error?
I think you are probably right. If an argument is bigger than 709 then EXP overflows. You need to identify the big numbers and decide how to handle them. See the second half of the blog post "Constants in SAS" for how to prevent the overflow.
I get it. Thanks!
You might also want to ask yourself WHY you are getting these overflows. Are you trying to evaluate a probability dentiy function (PDF) for an observation that is way out in the tail? The PDF for those observations is zero. Fitting a model to data? Maybe the model isn't appropriate for those data.
