A few years ago, taking testimony in a court case, an attorney asked me, “Tell me, doctor, have you heard the saying, ‘Lies, damned lies and statistics’? Isn’t it true what they say, that you can lie with statistics?” I answered, “Not to me, you can’t.” My point that day was that if the person…
Every day, I get email asking me if I am interested in some affiliate program, link exchange, blah, blah, blah. Obviously, these people do not read my blog because I personally would question the wisdom of affiliating oneself with a person who has called a congressman a lying ass mother-fucker (I was right, too) and…
It’s not often that you read a paragraph and it sticks in your mind for months. That this particular paragraph came not from some great literary work but rather from the proceedings of the annual meeting of the Association of Small Computer Users in Education is even more expected, but there it is. Douglas Kranch…
I have a confession to make. As a sixteen-year-old college freshman, I had no idea what people in business did. As a nineteen-year-old college graduate, with a BSBA, I didn’t know much more. My more affluent classmates had internships in the summer. My scholarship covered my tuition and sometimes room and board but left a…
Continuing to learn Advanced SAS from the Propensity Score Matching with Calipers macro from Feng, Yu & Xu , we take our data set we created by doing a principal components analysis on the cases (experimental) group, using the coefficients from that analysis to score every record in our control group, concatenating the cases and controls,…
This is part 3 (hence the name) of my posts on how to learn advanced SAS from other people’s code. Yes, taking a class is a good idea – I have taken several – a couple from SAS Institute here and there, several before or after conferences like WUSS and SAS Global Forum. For me,…
Okay, where we left off on the propensity score macro from Feng, Wu and Xu and the nifty things you can learn from reading someone else’s code, in this case, their propensity score macro with calipers …. We previously dealt with the situation where you had no matches and exactly one match. If you find…
We had a cat named Beijing. “Had” is the key word in that sentence. This weekend I dropped Bejing off to live with my daughter, Jenn, who actually likes cats in general and this cat in particular. The main reason (besides that Jenn wanted her) is that the cat always wanted to sit on my…
I thought my day today would be easy. There is a FUZZY module that goes with the SPSS integration for Python. All I needed to do was install the SPSS Python Integration technologies, then, maybe install the fuzzy plug in and it would all work. Both the rocket scientist and I worked on this most…
I was using a macro this week written by Feng, Yu & Xu and there were so many less-used and advanced techniques in it I thought it would be a great example to use for teaching SAS. ** ** Nifty thing one computing the caliper width ***** ; Like with other propensity score macros, it…
