LOG-DAY MODEL + COHEN'S f + POWER -- unmerge_d6_10 [metric: # successes (count)]
|
|
==============================================================================
|
|
model: behavior ~ stim + log(day) + stim:log(day) + (1|rat) (behavior = # successes (count))
|
|
log(day) uses 1-indexed training day (our day 0 = paper "Day 1")
|
|
observed groups: stim n=3, control n=2 nrep=120, alpha=0.05
|
|
|
|
--- fitted on real data ---
|
|
stim x log(day) interaction: F(1,21)=0.581 p(resid)=0.4545 p(Satt)=0.4549 (df=20)
|
|
honest per-animal random slope (log-day): F(1,5.0)=0.44 p=0.5382
|
|
Cohen's f (interaction, partial eta^2=0.011) = 0.106 (small-medium; f: .10 small, .25 medium, .40 large)
|
|
|
|
--- power simulation (log-day ground truth: stim:logday=+16.98, ratSD=6.081, resSD=8.718) ---
|
|
|
|
true stim:log(day) = +16.98 (100% of observed)

Read per-animal as the honest power; LME matches the paper's power code (optimistic).
