Variable Transformations |
Figure 32.15 shows the transformations that are available when you select Scaling/Translation from the Family list. These transformations are used to center and scale a variable. Equations for these transformations are given in Table 32.5.

Default | Name of | ||
---|---|---|---|
Transformation | Parameter | New Variable | Equation |
center(Y) | Center_Y | ||
stdize(Y) | Stdize_Y | See text. | |
reflect(Y;a) | Reflect_Y | ||
a+b*Y | Linear_Y |
The stdize(Y) transformation transforms the data to have zero mean and unit variance.
The reflect(Y) transformation reflects the data about the value .
