Finding homoscedasticity in a linear model
I am being asked if just according to this single plot (residuals vs fitted) of a linear regression is enough to determine if homoscedasticity exists in the linear model. I know that all residuals should be around zero independently of our fitted values but it's a bit tricky in this one! Thank you so much!
