    1. Outcome is log-transformed (Log–Lin) Model Interpretation 2. Predictor is log-transformed (Lin–Log) Model Interpretation 3. Both outcome and predictor log-transformed (Log–Log) Model Interpretation 📊 Quick Reference Table Model Equation Coefficient meaning Log–Lin ln y = β₀ + β₁ x 1 unit x → ≈ 100 β₁ % change in y (exact 100(e^{β₁}−1) %) Lin–Log y…
