Sometimes the free disk space can be deceptive. A simple sort requires over 4x the disk space of the original data set: http://support.sas.com/kb/15/065.html A long SAS job with lots of work data sets can eat up a lot of disk space; since the WORK library gets cleaned up when you exit SAS, you don't know the space that was being used. You might want to try using the TAGSORT option. It requires one extra read of the dataset, but uses much less disk space. That HotFix bundle is also just two weeks old, so it may have introduced that error as a side effect. It's rare with SAS, but I have had it happen. ... View more

In GLM, you can use the "bar operator" (|) to get all possible interactions. I suspect that syntax would work in MIXED as well. Check the syntax in the MODEL statement. Doc Muhlbaier Duke ... View more

Actually, it's not a bug. y**x, where y is a negative number, is called a discontinuous function -- it is not defined for every value on the real line. For instance, (-4)**2 is well defined (16), but (-4)**(1/2) (e.g. the square root of -4) is unknown. In Black's case, my guess is that when (-3)**(-3) is rendered, SAS gets the exact value 3, but there is some rounding in the repeated additions in the do-loop, and then the discontinuous nature of using a negative base comes into play. SAS gives an invalid argument error message for the results it could not compute. Doc Muhlbaier Duke ... View more

x = today() - 365; FORMAT x date9. will set "x" to one year ago today. In SQL, that is just SELECT (today() - 365) AS x You can add the format too in SQL, the syntax is in the manual. ... View more

the simple way is to change the format to "1: Early", etc. If you don't want it to show in the printout, you could prefix the word with non-printable characters to effect the sort order. ... View more

What version of SAS? The use of the OUT= changed between 8.2 and 9.2. See page 2888 http://support.sas.com/documentation/cdl/en/statugkde/61796/PDF/default/statugkde.pdf ... View more

The only way to get a CI on the interaction is to recode the data with the IA as a "main effect" ABia=a*b; and include it in the model as a separate variable. Although you can technically get a CI that way, it's nearly impossible to interpret. Good luck with that. If A & B are binary, it's OK, but beyond that is a stretch. ... View more

SASbase, Cynthia just gave you the shell of a program to read the data. It's what I did some years ago when I had to work with HL7 data. Once you've determined the record type (the seg #), you can use the usual SAS input statements to get the data in. As I recall, the person identifier is on one of the early seg's, so you'll need a RETAIN to save that for each output record. Doc Muhlbaier Duke ... View more

If you have delimited files, you are looking at some detailed data step programming. There are several versions of the HL-7 standard and they have some differences in formatting so be sure the documentation matches the data. As far as seeing one long data record, that may be a source data compatibility problem. Some operating systems do not separate "records" by a CR or a CR+LF-pair delimiter. You may need to work closer on the format with your data provider on more detailed formats. ... View more

If you really want to compare means, you are in the world of parametric statistics. Most of the non-parametric tests examine medians or other characteristics of the distribution. Friedman's 2-way analysis of variance can handle some types of repeated measures without assuming normality. I'm not sure whether or where it is in SAS. If you have enough data, you could convert the outcomes to ranks and rely on the central limit theorem to support conclusions based on a parametric analysis. You might also be able to use a variance stabilizing transformation and apply the parametric methods. ... View more
