Commentary: “Measurement Error Models in Astronomy” by Brandon C. Kelly
Bayesian analysis offers a general approach to measurement error that has many advantages—it focuses attention on careful modeling, is widely applicable, and provides efficient estimators. Bayesian analysis is relatively easy using WinBUGS software. We discuss here the paper by Brandon Kelly, and present an example of fitting a quadratic regression model with WinBUGS called from R, with the WinBUGS and R code provided.
