Step 4: Transform the Function into a Linear Equation

E.g

Assumed Equation

Import Data to Excel

Correlation Matrix?

Transform into Linear

Prepare Data Table

Regression by Excel

Quality Analysis

No

Yes

ln (ODijk) = ?0 + ?1 ln(EMPi EMPj)
+ ?2 ln(FAij )

y = ?0 + ?1 x1 + ?2 x2

ODij = e?0* (EMPi EMPj)?1 * (FAij )? 2
