In a regression analysis,if a new independent variable is added and R-squared increases and adjusted R-squared decreases precipitously,what can be concluded?在回归分析中,如果有一个新的变量x加入,那么r的平方增大,同时调整r方减小,以下推论哪个是对的The new independent variable improves the predictive ...
mse1 is used only in programs and ado-files that use regress to fit models other than linear regression and is not allowed with the svy prefix. mse1 sets the mean squared error to 1, forcing the variance–covariance matrix of the estimators to be (X DX)−1 (see Methods and formulas...
