Select the MOST appropriate reason multiple regression coefficients are called conditional coefficients:" The estimated coefficient of one independent variable depends on the other exogenous variables O The expected value of the random errors are is not equal to zero O The independent variables are always linearly related The estimated coefficient of one independent does not depend on the other exogenous variables In a multiple regression analysis, the Mean Square Regression ("MSR") is: O Total sum of squares divided by the number of independent variables O Regression sum of squares divided by the number of independent variables O Regression sum of squares divided by the degree of freedom Residual sum of squares divided by the number of independent variables
