HONEST LME (per-animal random slope, day|rat): interaction F(1,5.0)=0.01, p=0.9219
|
|
(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 n.s. -- slopes parallel (no differential learning rate) (p=0.8895, slope diff=+0.002261)

Paper (N=24, count): interaction t(227)=2.68, F(1)=7.12, p=0.008.
