Webb14 dec. 2024 · In other words, such a regressor is explaining a lot of the data’s variance. Sometimes two regressors account for the data equally well, but it’s unclear whether this is because they’re explaining the same parts of the data (shared variance), or different parts (unique variance). You can also think of this as a venn diagram (Figure 1). WebbI don't agree with this procedure, but it is often used for determining the discriminant validity. Cite. 15th Aug, 2016.
