Which test can I use for analyzing the effect of a categorical independent variable, such as preoperative ASA score (1/2/3/4), on a binary dependent variable, such as postoperative complication (yes/no)?
I know that the chi squared test is an option, but this test does not tell me if the significant difference lies between ASA 1 and ASA 2 or between ASA 2 and ASA 3,...
Is there a statistical test I can use to know between which independent categories the significant difference is situated?
