Note. Effect tests for ordinal logistic model of friend-rank. Friend-rank and perceived rank variables were transformed by multiplying by −1.

a

Standardized logistic regression coefficient. The exponential of β is the change in the odds of being ranked a better friend for each unit (SD) increase in the associated predictor.
