LOG-DAY MODEL + COHEN'S f + POWER -- unmerge_d0_10 [metric: success RATE]
|
|
==============================================================================
|
|
model: behavior ~ stim + log(day) + stim:log(day) + (1|rat) (behavior = success RATE)
|
|
log(day) uses 1-indexed training day (our day 0 = paper "Day 1")
|
|
observed groups: stim n=3, control n=3 nrep=120, alpha=0.05
|
|
|
|
--- fitted on real data ---
|
|
stim x log(day) interaction: F(1,57)=9.174 p(resid)=0.003684 p(Satt)=0.003695 (df=57)
|
|
honest per-animal random slope (log-day): F(1,35.1)=8.84 p=0.005302
|
|
Cohen's f (interaction, partial eta^2=0.030) = 0.177 (small-medium; f: .10 small, .25 medium, .40 large)
|

|
--- power simulation (log-day ground truth: stim:logday=+0.08869, ratSD=0.04059, resSD=0.08029) ---
|
|
|
|
true stim:log(day) = +0.08869 (100% of observed)

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