forwards stepwise regression,就是不断的往里面加变量,使得t statistic最显著;缺点很明显:1.多次检验,会加入过多变量;2.找不出复杂搭配的模型,因为是一个一个添加的; backward stepwise regression,全部引入,然后一个一个的减;缺点:1.共线性; mixed stepwise Diagnostics方法,如何确定我们的基本假设是对的,假设都...

The information in an ANOVA table is used to attribute the total variation of the dependent variable to one of two sources: the regression model or the residuals. This is indicated in the first column in the table, where the "source" of the variation is listed. The information in an ANOVA...
Multiple Regression Multiple Regression is a special kind of regression model that is used to estimate the relationship between two or more independent variables and one dependent variable. It is also called Multiple Linear Regression(MLR).

The multiple regression model allows an analyst to predict an outcome based on information provided on multiple explanatory variables. Still, the model is not always perfectly accurate as each data point can differ slightly from the outcome predicted by the model. The residual value, E, which is...
