Parallel groups in bear - CIs [🇷 for BE/BA]
Ahoy ElMaestro!
(underlined by me )
There is a hint I meanwhile discovered:
Also the summary() function works on the lme-model intervals() does not:
Only the fixed effects parameter can be obtained, astonishing enough :
Seems to me as there is something wrong with the random part.
❝ In my opinion, and I could be wrong, with this specification of the model we are not trying to do exactly that [...]

There is a hint I meanwhile discovered:
Also the summary() function works on the lme-model intervals() does not:
> intervals(lmeModel, level=0.9)
Error in intervals.lme(lmeModel) :
Cannot get confidence intervals on var-cov components: Non-positive definite approximate variance-covariance
.Only the fixed effects parameter can be obtained, astonishing enough :
> intervals(lmeModel, which="fixed", level=0.9)
Approximate 90% confidence intervals
Fixed effects:
lower est. upper
(Intercept) 6.9615133 7.10189 7.2422667
drug2 -0.1825826 0.01594 0.2144626
Seems to me as there is something wrong with the random part.
