SOME INFERENCES AND EXPERIMENTS ON FREE KNOTS SPLINE REGRESSION. Authors: PETRU P. BLAGA. |
||||||
Abstract: Inferences and experiments on the simple spline regression with free knots are considered. For the first time an iterative procedure given n [2] to estimate the values of the free knots based on a multiple lnear re- gression is recaled. Point estimators and confidence interval estimators on the splne regression coefncients and variance of the response, confidence nterval estimators and (Scheffe [7]) simultaneous confidence interval esti mators on the mean value response and prediction value are considered. Inferences are iustrated by some numerical experiments. | |||||||
