LOG-DAY MODEL + COHEN'S f + POWER -- prev_f_full [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=12, control n=12 nrep=120, alpha=0.05
|
|
|
|
--- fitted on real data ---
|
|
stim x log(day) interaction: F(1,227)=8.356 p(resid)=0.004218 p(Satt)=0.004253 (df=208)
|
|
honest per-animal random slope (log-day): F(1,24.3)=3.32 p=0.08079
|
|
Cohen's f (interaction, partial eta^2=0.012) = 0.112 (small-medium; f: .10 small, .25 medium, .40 large)

--- power simulation (log-day ground truth: stim:logday=+2.389, ratSD=4.328, resSD=4.338) ---
|
|
|
|
true stim:log(day) = +2.389 (100% of observed)

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