Moreover, with just 2 non-ordinal variables, instead of using regression, you might be better off looking at chi-square and its related measures of association such as Cramer's V. – rolando2. Witryna9 wrz 2024 · If you get the odds ratio from the logistic output in the paper you reference, call this O R. Then you can find the predicted proportion with response for a one-SD higher group of X by first calculating this O d d s 1 S D = p / ( 1 − p) ∗ O R S x Odds-1SD is the odds of response at one SD higher value from the "center".
