The value of b1is the slope of regression line of Y against X1. Same is the case with b2, b3and so on. These values are then used to minimize the difference between actual and expected value of Y. The difference gives rise to another parameter called Coefficient of Multiple Regression (...

partial regression coefficient: a value indicating the effect of each independent variable on the dependent variable with the influence of all the remaining variables held constant. Each coefficient is the slope between the dependent variable and each of the independent variables p-value: The probabilit...

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 regression coefficient is negative and indicates that white patients have 0.9161 subtracted from their percent body fat. The intercept itself is –8.3748, meaning that the predicted percent body fat is reduced by this amount after including all variables in the equation. The regression ...
