Anyone who doesn't know stats, this is just going to seem weird to you.

This "summer" research has bled into my school year, is fucking with my studies, and now I have to have a poster ready by Friday and STILL need to do this regression analysis. I was taught in my stats class that logistic regression could be used as a way of "holding other variables constant" in order to expose the effect of a true independent predictor. In this way, we can sort of control for confounding right?? So far all the tutorials I'm seeing aren't explaining how this keeping constant thing works. It just seems like a way to look at multiple effects at once and see if they are significant, as opposed to doing chi squares for each one. There's GOT to be more to it than that. THat's what I was told. ffs

Look, I want to see if patients who come from nursing homes have worse outcomes after surgeries than those that come from private homes. Let's say my one question is if they end up dying more often 30 days after surgery. I did a chi square. The answer is YES. Yes, patients who come from nursing homes end up dying 30 days after surgery more frequently than those who don't. Now I want to see if things like age or functional status are confounding that finding. HOW FOR TO DO
