Next we try WLS estimates since. 0136 0217 Because of this nonconstant variance we will perform a weighted least squares analysis. For more information about.
Chi2 03486 Prob.
0136 0217 Because of this nonconstant variance we will perform a weighted least squares analysis. Weighted least squares provides one method for dealing with heteroscedasticity. But the normal use of weighted least squares weights an observation in inverse proportion to its variance. Weighted Least Squares in Simple Regression The weighted least squares estimates are then given as 0 yw 1xw 1 P wixi xwyi yw P wixi xw2 where xw and yw are the weighted means xw P wixi P wi yw P wiyi P wi.
