1. ### Sample size calculation to detect mortality benefit of treatment

Mortality will be collected at day 14 and 30 from the day of diagnosis, which is almost always the day of initiation of treatment in my context. Not sure of the relevance of controlling for "time to event". Seems like I've forgotten the little stats that I used to know.

Any help?
3. ### Sample size calculation to detect mortality benefit of treatment

Hi folks, I was wondering if you could help me with this. I thought I'd be able to work this out but my stats knowledge is very jaded now. If the mortality rate from an illness is 2% and I want to conduct a trial comparing treatment X with placebo, with a view to finding out whether treatment...

Can't say I understood most of your replies but thanks.
5. ### Does SAS run on Samsung Galaxy Tab S4 ?

noetsi is it possible to install the full version of SAS (not university edition) on microsoft surface Go? Thanks.
6. ### Does SAS run on Samsung Galaxy Tab S4 ?

What would you do with SAS if not run stats? Galaxy is Android based. (I'm just worried the tablet may not be powerful enough to handle SAS...moreover, if I remember correctly, CDs were needed when I got SAS installed on my ancient laptop many years ago).
7. ### Does SAS run on Samsung Galaxy Tab S4 ?

Does SAS 9.3 and above run on Samsung Galaxy Tab S4 or any other tablet? Many thanks.
8. ### How much of Science is based on Statistics

I vaguely remember the Higgs Boson experiment at CERN from the news actually and the p-values quoted were 0.---many many zeros and then a one and I remember thinking that most of Medicine allows for a huge probability of a chance result by comparison. Anyway, we all understand that for obvious...
9. ### Error-rate before and after (which statistical test)

Guys any insights will be much appreciated.
10. ### Error-rate before and after (which statistical test)

Thanks Karabiner. Question: Is the prescription error-rate significantly different after the introduction of electronic prescribing? Data will be collected retrospectively. There is already in place a system to report prescription-errors. It was in place before and has remained in place after...
11. ### How much of Science is based on Statistics

Very random and possibly silly question, but then this is random chat. We'll add silly to it. Does Physics use statistics and probability as heavily as Medicine does? My guess is No. In Medicine, we're limited in that we can't experiment in most situations and therefore end up with...
12. ### Error-rate before and after (which statistical test)

Guys I've done advanced analysis a long time ago and my statistical sense is now rusted. I couldn't come up with confident answers on a quick review and would appreciate input. What would be the correct statistical test for comparing prescription-error rate before (1 year before, duration 1...
13. ### SAS on Mac

It's because I've never used R and I don't know how it works. Neither I nor my colleagues are statisticians so I have no one to ask.
14. ### SAS on Mac

Does anyone have experience with SAS on Mac? Does it work okay?
15. ### Regression diagnostics with proc glm or proc reg

I fit my model using 'proc glm' but now it seems that proc reg should be used for the diagnostics. So, do I need to fit the model all over again using proc reg and creating dummy variables (that proc glm avoided) since proc reg is to be used for the diagnostics or can diagnostics be done with...
