| Jun 18, 2019 at 20:43 | comment | added | StatsScared | thank you. Would you mind expanding, or providing a source to dig deeper, on your comment that "interactions are in general less precisely estimated than main effects." Also, you say 'If they involve categorical main effects they can lead to unexpectedly high loss of degrees of freedom.' -- perhaps I am missing something, but why is it an unexpected high loss of df? | |
