LOG-DAY MODEL + COHEN'S f + POWER -- naive_boxa_d6_13 [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(1,69)=0.239 p(resid)=0.6263 p(Satt)=0.6264 (df=65)
|
|
honest per-animal random slope (log-day): F(1,9.1)=0.07 p=0.8013
|
|
Cohen's f (interaction, partial eta^2=0.001) = 0.034 (small; f: .10 small, .25 medium, .40 large)

|
--- power simulation (log-day ground truth: stim:logday=+6.701, ratSD=10.78, resSD=11.38) ---
|
|
|
|
true stim:log(day) = +6.701 (100% of observed)

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