How to detect heteroscedasticity in the regression model?

Look at the residual plots against each independent predictor. A “V” or “U” shape pattern indicates that the error terms do not have homogeneous variance. true or false

To detect heteroscedasticity in the regression model we have some true conditions like,

We have to check if the regression model is linear and there is no ommitted variables.
We have to test equality of variances using the Lack of fit test

So, The condition which is given in the question that is " Look at the residual plots against each independent predictor. A “V” or “U” shape pattern indicates that the error terms do not have homogeneous variance" will not allow to detect heteroscedasticity in the regression model so this condition is false.

Tell what each of the residual plots to the right indicates about the appropriateness of the linear model that was fit to the data (a) Choose the best answer for residuals plot (a).A. The scattered residuals plot indicates an appropriate linear model.B. The curved pattern in the residuals plot indicates that the linear model is not appropriate. The relationship is not linear.C. The fanned pattern indicates that the linear model is not appropriate. The model's predicting power decreases as the values...

True or False 1) in a population regression model, we assume the errors are independent of each other and normally distributed with constant variance 2) when we apply the ordinary least squares to estimate the slope and intercept of a linear model, the sum of all the residuals can be less than or greater than zero 3) if SSE is near zero in a regression, the statistician will conclude that the proposed model probably has too poor a fit to...

Assume one has estimated a regression equation of salary (dependent variable) against years of education independent variable). How would one go about expanding the regression model to also estimate the gender effect (i.e., the average difference between male and female salary, given the same level of education? Explain how you would construct the additional variable and how you would interpret it, given how you construct it. How would you construct a hypothesis test to determine if the estimated gender-based differential...
