Group effects EMA [Two-Stage / GS Designs]
Hi Mittyri,
That's kind of incorrect.
The more effects you have in your model, the more variation is accounted for by the totality of terms; the residual will decrease as will be residual's degrees of freedom. Therefore the width of the CI tends to shrink.
It may happen that the inclusion of a term apparently does nothing. This is due to the design where some effect may contain the other; in such situation the residual variance, the residual df and the width of the CI remain unaffected. But you will never see the CI widened due to more factors.
❝ More effects in model mean wider intervals.
