HONEST LME (per-animal random slope, day|rat): interaction F(1,67.1)=4.40, p=0.03968
|
|
(Satterthwaite DF ~= residual on this random-intercept model; the random-slope
|
|
model above is the honest learning-rate test -- DF collapses toward the animal count.)
|
|
INTERPRETATION: stim x day interaction SIGNIFICANT positive -- treatment improves FASTER (benefit accumulates) (p=0.04062, slope diff=+0.01393)
|
|
Paper (N=24, count): interaction t(227)=2.68, F(1)=7.12, p=0.008.
