Question

Which of the following is NOT a part of regression specification? A) Selecting the dependent variable. B) Identifying important independent variables. C) Explaining expected signs for the coefficients of each independent variable. D) Forecasting the expected value of R2 for your model.

]In a multiple regression model, the intercept or constant (b0) A) forces the regression line to go through the origin (point where dependent variable is zero when the independent variable is zero). B) is typically unimportant in interpreting the model so can be omitted from model with little effect on results. C) measures the portion of variation in the dependent variable that is explained by the variation in all the independent variables. D) Provides flexibility so the least squares method can estimate the best line fit for data in the relevant range of firm operations.

In a multiple regression model, the adjusted R2 A) can be negative. B) must be positive. C) has to be larger than R2. D) can be larger than 1.

Explanation / Answer

In the above question having three section D is not a part of the regression analysis because we can't forecast the R2 for the given model.

Section 2 : In multilple regression analysis , for the given statements , A statements is not sutable for the multiple regression , we can't forced the regression line passing through the origins.

Section 3

adjusted R2 is never be negative value because it is a sum of the square of the residuals and also not larger than one. hence statement A and D are not correct for the regression models.

section 1 : in the linear regression , the given statements the
