Proportion of Variance Explained

Figure 1. Proportion of variance explained
Proportion of variance explained

The proportion of variance explained table shows the contribution of each latent factor to the model.

  • The first factor explains 20.9% of the variance in the predictors and 40.3% of the variance in the dependent variable.
  • The second factor explains 55.0% of the variance in the predictors and 2.9% of the variance in the dependent.
  • The third factor explains 5.3% of the variance in the predictors and 4.3% of the variance in the dependent. Together, the first three factors explain 81.3% of the variance in the predictors and 47.4% of the variance in the dependent.
  • Though the fourth factor adds very little to the Y variance explained, it contributes more to the X variance than the third factor, and its adjusted R-square value is higher than that for the third factor.
  • The fifth factor contributes the least of any factor to both the X and Y variance explained, and the adjusted R-square dips slightly. There is no compelling evidence for choosing a four-factor solution over five in this table.
