R2 does not have the same meaning as for unweighted least squares. Example: Fit a regression model using weighted least squares (weighted_least_squares.R) Below is how I simulated some data to illustrate nonconstant variance. > #Simulate data with nonconstant variance > X set.seed(8128)

You may also consider weighted least squares regression instead of Ordinary Least Squares regression. The errors are independent of X. This sounds like homogeneity of variance to me. Pedhazur states that these assumptions are necessary for the obtained estimators to be “best linear unbiased estimators.” If t or F will be employed for tests ...

The R-squared in the weighted least squares estimation is larger than that from the OLS regression in part (i), but, remember, these are not comparable. (iv) With robust standard errors – that is, with standard errors that are robust to misspecifying the function h(x) – the equation is
