This article discusses how to use SAS to filter variables in a dataset based on the percentage of missing values or duplicate values. The missing value statistics can be implemented by either DATA step programming on your own or reusing the existing powerful PROC FREQ.
How to filter variables by percentage of missing values or duplicate values in SAS was published on SAS Users.
A ghoulish Halloween Boo to all my readers! Hope my costume freaks you out, but even if it doesn’t, I’m positive PROC FREQ will in a few amazing ways! Today’s Programming 2: Data Manipulation Techniques class asked about the power of PROC FREQ. Since I stopped to explain some of it’s benefits to […]

I planed to extend nonWinferiority testing to one of my statistical notes, Equivalence Testing and TOST (Two One-Sided Test) since noninferiority test is simply half part of the equivalence test. Today I’m glad to find an even better explanation from SAS Usage Note 48616: Design and analysis of noninferiority studies You will love it if […]
There SAS applications/procedures/features were not necessarily available since 2012. This year I paid special attention to them when began to use SAS 9.3. The following notes are totally my personal endorsement purely based my own experience as a user: XML File Reading: SAS XML Mapper SAS XML Mapper itself is not an elegant tool from […]
In some settings it may be necessary to recode a categorical variable with character values into a variable with numeric values. For example, the matching macro we discussed in example 7.35 will only match on numeric variables. One way to conve…
A guy notices a bunch of targets scattered over a barn wall, and in the center of each, in the "bulls-eye," is a bullet hole. "Wow," he says to the farmer, "that’s pretty good shooting. How’d you do it?" "Oh," says the farmer, "it was easy. I painted the targets after I shot the holes." […]
A latest updated post on Freakonomics, Beware the Weasel Word “Statistical” in Statistical Significance!, seemed to attempt to challenge frequentist statistics by Bayesian. I have no research on Bayesian and won’t jump to the debates. I’d rather to use this case to apply the Dragon’s Teeth and Fleas logic of hypothesis testing (at least I […]
