Bayesian Comparison of Two Regression Lines

Robert K. Tsutakawa

Journal of Educational and Behavioral Statistics, 1978, vol. 3, issue 2, 179-188

Abstract: The comparison of two regression lines is often meaningful or of interest over a finite interval I of the independent variable. When the prior distribution of the parameters is a natural conjugate, the posterior distribution of the distances between two regression lines at the end points of I is bivariate t. The posterior probability that one regression line lies above the other uniformly over I is numerically evaluated using this distribution.
