Wouldn't this just be a binomial proportion 1 sample test? Since the HSRANK would have different percentiles of < 82 ranking, and otherwise, per "Year that the student entered high school." Since you're taking random samples each time you test lrank/hrank wouldn't there be some difference in proportion? I am equally as confused with this set of questions. ... View more

I'm relatively new to SAS programming so I'm having trouble understanding some of your code. I'm having trouble understanding the purpose of the first 2 do loops. Why is the variable 'n' 10^e? Also, why does the second do loop go from 1 to 9-e. Does the code below do the same thing but in a simpler way?  data pieces; call streaminit(23456); do i= 1 to 100000; r= rand('uniform'); short = min(r,1-r); long = max(r,1-r); output; short_long = short/long; long_short = long/short; end; run; data status; set pieces; row = _n_; SL_Running + short_long; LS_Running + long_short; SL_Mean = SL_Running / _n_; LS_Mean = LS_Running / _n_; run;     ...

So by looking at the graphs, the expected value of short divided by long converges because the values converge towards a single value. While the expected value of long divide by short diverges because it doesn't converge towards a single value? Expected Value of Long Divide by Short Expected Value of Short Divide by Long ...

I changed the r variable right before inserting it. The randnum variable should be r.  How would I create a running mean?   data pieces; call streaminit(12345); do i = 1 to 50000; r = rand('uniform'); short = min(r, 1-r); long = max(r, 1-r); output; short_long = short / long; long_short = long / short; end; run;   proc means data=pieces; var short_long long_short; run;   ...
