They focus on finding groups of variables that might contribute individually to multicollinearity, yet be relatively uncorrelated between groups. | |

Dec 2, 2022 at 12:55 | comment | added | BigBendRegion | A "chunk" can be highly significant while variables within the chunk are insignificant, due to multicollinearity of variables within the chunk. So variance inflation does not seem to be an issue for the chunk test, despite collinearity within the chunk. As an example, there is perfect multicollinearity between variables in the full dummy representation of a factor, but the partial F test is not affected. On the other hand, if there is multicollinearity between chunks, there will definitely be a variance inflation issue. Seems like interesting math involving a cross- correlation matrix. | |
