| 内容記述 | In regression analysis a traditional approach, the so-called constrained coefficient approach, is usually used for model selection. We propose a new approach, named as constrained coefficient-component approach, instead. The constrained coefficient-component approach is developed based on a basic model which contains all of the explanatory variables that may be available and will be meaningful for practical applications. The procedure for the constrained coefficient-component approach is as follows. Firstly, we define a vector of coefficient-components by using an orthogonal transformation of the vector of regression coefficients in the basic model. Then, we construct a number of contending models by constraining some coefficient-components to be zeros. Further, the best model among all the contending models is selected by using Akaike information criterion, AIC. The constrained coefficient-component approach has many advantages, e.g., (1) the total number of the contending models can be reduced so that the process of model selection becomes really easy; (2) by using the newly-proposed approach we can obtain more stable estimation for parameters and a model that has better performance measuring by AIC. The constrained coefficient-component approach is applied to analyzing the influence of temperature on productivity of rice production in Hokkaido as an example. | |||||||||
