As we can see from the Table above the following items are skewed: SIQ, Cust.NPD, CF, Fair, Sales<br />

RP. To correct for the skewness we took a square root of the above variables. After the squareroot transformati<strong>on</strong> the skewness to st<strong>and</strong>ard error<br />

ratio is acceptable. The new variables are labeled as follows: SIQ.Sqr, CUST.NPD.sqr, CF.Sqr, Fair.Sqr, Sales.Sqr,<br />

RP.Sqr.<br />
