Abstract: | A Bayesian approach is considered to detect a change-point in the intercept of simple linear regression. The Jeffreys noninformative prior is employed and compared with the uniform prior in Bayesian analysis. The marginal posterior distributions of the change-point, the amount of shift and the slope are derived. Mean square errors, mean absolute errors and mean biases of some Bayesian estimates are considered by Monte Carlo methad and some numerical results are also shown. |
