<strong>Regressione</strong> vincolata:<br />
TestScore = 644.7 –0.671PctEL, SQR V = 0.4149<br />
(1.0) (0.032)<br />
<strong>Regressione</strong> non vincolata: k = 3; q = 2<br />
TestScore = 649.6 – 0.29STR + 3.87Expn – 0.656PctEL<br />
(15.5) (0.48) (1.59) (0.032)<br />
SQR NV = 0.4366;<br />
Quindi:<br />
