I barely make comments on youtube. I have to say, this is one of the best videos I have watched on the concept. very straight to the point, and summarized.
Question. Since Gender is a classification variable, unlike age which is continuous, wouldn't it be important to have gender in the class statement before the model statement?
Can you please show the code that you did for the proc logistic procedure, though? How do you know what to put in the class statement? I mean, when you use a class statement in proc logistic, what does that mean?
Interesting. I get similar, but different results using the same data set. Differences depend upon whether sex is classified in a Class statement, or considered numeric. I get identical odds ratio tests if sex is a "class" variable, although a different coefficient on sex (but same SE and p val). All other stats are the same IF I add a "class" statement for sex.
Thank you very much for a good explanation, there is my question : isn't a partial test equivalent to likehood ratio, I mean the values of chi-square and p - value are the same

yes, his explanation is very clarity to understand, i am not sure why the sound is very quiet on my end I can barely hear.
Echoing others. This video was, without a doubt, one of the best on You Tube - across any subject. Saved me a ton of work. Many thanks
Thank you for your explanation Sir. SAS tutorials are hard to find and some of them are even confusing. But this video is very clear.
Thanks a lot, it is really helpful in understanding SAS logistic results. Thanks from bottom of my heart

Really helpful video, thanks a bunch dude!

Hiya, just a question, (I may of missed it). @ 16.16 with the odds equation where are you getting the e value from to get an answer of 23.39? Thanks!
thanks
Great Job!
well explained.
shouldn't Age be treated like a class or ordinal variable
f-first :D
