You’ve settled on a regression model that contains independent variables that are statistically significant. By interpreting the statistical results, you can understand how changes in the independent variables are related to shifts in the dependent variable. At this point, it’s natural to wonder, ...

The data analyst confronted with a large number of variables from which he must select a parsimonious subset, as independent variables in a multiple regression, is faced with a number of technical issues. What criterion should he use to judge the adequacy of his selection? What procedure should...
1.This paper studies the important problem to select independent variable in regression analysis theory.本文研究了回归分析理论中的自变量选择的重要问题,利用线性回归模型自变量增减的残差平方和理论,获得了一种选择自变量的准则,该准则的分析表明,它计算简单,而且在一定的条件下具有强相合性。
heating system: for a 1%-point increase in heat pumps the share of fossil-fuel heating systems reduces by 1%-point and the coefficient times 0.01 estimates the difference between the effect of fossil-fuel and heat-pump systems on the dependent variable in a regression, such as average ...
In a simple regression analysis (where Y is a dependent and X an independent variable), if the Y intercept is positive, thenthere is a positive correlation between X and Yif X is increased, Y must also increaseif Y is increased, X must also increaseNone of these alternatives is correct....
