Note(s):

The R² and adjusted R² values assess the proportion of variance explained by the predictors in each endogenous variable. According to Hair et al. (2019), R² values of 0.25, 0.50 and 0.75 represent weak, moderate and substantial levels of predictive accuracy, respectively. Cohen’s f2 values determine the size of each exogenous variable’s effect, with values of 0.02, 0.15 and 0.35 interpreted as small, medium and large effects (Cohen, 1988)
