I don't think you're intended to use that data set. You need to use the data that's been filtered and set out to once a week - ie the data from a previous step in your assignment. ... View more

Definitely a couple of questions in order to get started ...   Your data set already contains RATE.  Is there any reason you still need SEIZURECOUNT for this report? How do you determine which records are "at baseline" ?  Could this be as simple as the program  below, or is there more to it? proc means data = epilepsy n mean; Var Age rate; run; ... View more

Didn't you already get an answer to this question on your other thread?  /* Variable List: Patient ID, Treatment (0=Placebo, 1=Progabide), Age, Baseline 8 week seizure count, First 2 week seizure count, Second 2 week seizure count, Third 2 week seizure count, Fourth 2 week seizure count. */ data mydata ; input id treatment age @; do period=0 to 4 ; if period=0 then weeks=8; else weeks=2; input count @; rate = count / weeks ; output; end; cards; 1 0 31 11 5 3 3 3 2 0 30 11 3 5 3 3 ; At least from the first two patients it looks like the rate has gone up on that treatment. ...

Don't write code until you know what you want to write. How can you convert a rate for 8 weeks or 2 weeks into a rate for 1 week? You can't. You could possibly make an estimate. weekly_rate = rate / number_of_weeks; Is that what you want to calculate? ... View more

You are describing a data transposition. Use proc transpose for that:   proc transpose data=sasdata.epilepsy out=sasuser.epilepsylong name=interval prefix=count; by patient_id treatment age baseline; var TSC1 TSC2 TSC3 TSC4; run; ... View more

I'm just not sure about the right code for this particular one   You could use this code to generate a number of randomizations of the prize.   proc plan ordered seed=89768; factors rep=10 door=3 / noprint; treatment prize=3 random; output out=want prize cvals=('Goat' 'Goat' 'Car'); run; quit; ...

Assign a random number to each goat and a car. The lowest random number goes in door #1, the second lowest random number goes in door number two, and ... Umm... you can figure out the rest. ... View more
