LOG-DAY MODEL + COHEN'S f + POWER -- naive_a2_d0_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=7 nrep=120, alpha=0.05
|
|
|
|
--- fitted on real data ---
|
|
stim x log(day) interaction: F(1,100)=4.633 p(resid)=0.03378 p(Satt)=0.03391 (df=95)
|
|
honest per-animal random slope (log-day): F(1,7.2)=2.24 p=0.177
|
|
Cohen's f (interaction, partial eta^2=0.010) = 0.101 (small-medium; f: .10 small, .25 medium, .40 large)

|
--- power simulation (log-day ground truth: stim:logday=+9.586, ratSD=8.17, resSD=14.84) ---
|
|
|
|
true stim:log(day) = +9.586 (100% of observed)

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