WebJul 26, 2024 · From the properties of the log-normal distribution, if ln Y ∼ N ( μ, σ 2) then we have Y ∼ Log-N ( μ, σ 2), which has median and mean given respectively by: M ( Y) = exp ( μ) E ( Y) = exp ( μ + σ 2 2). In a log-linear regression model you have the log-mean estimator μ ^ = β ^ 0 + β ^ 1 X, so substitution of your estimators gives ...
