📊 Panel Method Decision Tree
// input hasil 3 tests, dapat recommendation method + reasoning
Step 1: Chow Test
F-test CEM vs FEM. H0: intercept sama untuk semua unit.
P-value Chow
p < 0.05 (Reject)
p ≥ 0.05 (Gagal Reject)
Step 2: Hausman Test
χ² test FEM vs REM. H0: REM consistent.
P-value Hausman
p < 0.05 (Reject)
p ≥ 0.05 (Gagal Reject)
Step 3: BP-LM Test
LM test CEM vs REM. H0: σ²_u = 0 (CEM OK).
P-value BP-LM
p < 0.05 (Reject)
p ≥ 0.05 (Gagal Reject)

Next Steps
Run all 3 tests di software (R/Stata/Python)
Input hasil ke widget di atas
Implement recommended method
Tambah two-way effects (unit + year) untuk panel modern
Pakai clustered SE by unit (always)
Lapor 3 model (CEM, FEM, REM) di paper untuk transparency
