I have a strategic question related to the best way to handle missing data in my situation. The situation is a diagnostic model that is normally conducted in stages (as most probably are) usually testing the least expensive measures for targets and progressing to the more expensive. Generally this ...

Re: Importing data from Excel not working

I have done that with the file supplied with the tutorial. This works fine. I do not have Microsoft Access so I can not create my own file and try that.
