| Jun 25, 2012 at 23:34 | comment | added | Luna | Thank you so much Macro for your help! It looks great now! Depending the answer to my Q4, if my understanding of the b's is correct, then I guess I wanted to minimize the sum of the weighted sum of squared b's (if b's are indeed the distance between the overall intercept and the group-wise intercepts) and the weighted sum of the squared (within-group) residuals... | |

| Jun 25, 2012 at 21:06 | comment | added | Macro | Luna, I tried to fix this up so that it is readable (in its previous state it was extremely difficult to tell what was being asked). I tried to transcribe your estimating equation verbatim but I'm not sure I did it correctly since what is there now is difficult to make sense of - what argument is being minimized over? The $w$s? Do the fixed effects, ${\boldsymbol \beta}$, come into play anywhere? | |
