Abstract(in English) | In this study, we propose a Beyes-optimal prediction method on a piecewise linear regression model by Bayes decision theory. The computation of the prediction requires weighting the posterior probability of all patterns of regression coefficient changes and all ranges of the coefficients. Especially, the computational complexity of weighting the posterior probability of all the coefficient changes is exponential order. Therefore, we propose a method of reducing the computational complexity by lumping coefficient changing patterns together if the change points before and after the data point to be predicted coincide. |
