Tests of significance of a single partial regression coefficient in a multiple regression model are often made in situations where the standard assumptions underlying the probability calculation (for example assumption of normally of random error term) do not hold. When the random error term fails to...
In short, the addition of independent variables to the regression model does not affect the equations for computing either the predicted values or the errors of prediction.doi:10.1007/978-0-585-25657-3_19Michael Patrick AllenSpringer USAllen, M. P. 1997. The coefficient of determination in ...
The coefficient of determination, r squared, in a multiple regression equation is the: a. Coefficient of the independent variable divided by the standard error of regression coefficient. b. Percentage of variation in the dependent variable explained by the variation in the independent variables. c....

The multiple correlation coefficient generalizes the standard coefficient of correlation. It is used in multiple regression analysis to assess the quality of the prediction of the dependent variable. It corresponds to the squared correlation between the predicted and the actual 关键词: BAYESIAN INFERENCE...

Many robust regression estimators are defined by minimizing a measure of spread of the residuals. An accompanying R 2-measure, or multiple correlation coefficient, is then easily obtained. In this paper, local robustness properties of these robust R 2-coefficients are investigated. It is also shown...
