Thanks.  I hadn't seen anything on how to do it in SAS either but wasn't sure if anyone else had any experience using it.  R would be fine (since it's open source) so I'll contact him directly and see what else I can gather.  I have to admit tho, it doesn't leave me with a "warm-fuzzy" feeling when I can't find anything on how to program the method.  Almost makes me hesitant to use it at all...but alas, that's not necessarily my call to make. Thanks for the info! ... View more

How about: [pre] proc freq data=data; tables a*b /chisq riskdiff; run; [/pre] riskdiff will give difference in proportion and its limited interval. Ksharp ... View more

What the LOGISTIC procedure is saying is that you have an over-parametrized model. To fix that you either need more data (so all the combinations are represented) or fewer variables. If Radical is defined at any one of Abdominal, Laproscopic, or Vaginal, then just drop Radical, as you can estimate it's effect via the other parameters. Doc Muhlbaier Duke ... View more

The code statement is the %INCLUDE, not the specific PROC FORMAT. If you have access to the actual PROC or DATA step code-piece, you can always insert this statement: OPTIONS NOSOURCE NOSOURCE2; More information is needed to explain the SAS programming technique used, such as whether a MACRO is defined or open SAS code? Try the OPTIONS above - you will want to verify that there is no other OPTIONS statement being invoked within the vendor code. Scott Barry SBBWorks, Inc. ... View more

Thanks Cynthia! I had found that paper yesterday and that's how I circumvented the problem - summarized the data ahead of time and then used that as an ORDER variable and that worked perfectly. Thanks for the response. Sue ... View more

The first thing that I can't seem to control is the height and width of the area in gslide.  For example, if I change a couple of the y values to 110 or so (yes, a pointless shape, but please try it), a large part of the shape's area is off the graph entirely.  What options need I throw at gslide so that the graph area expands to include larger numbers? ...
