           pmax  .

           PMax in STATISTICA.

              The  presence  of the equal sign, preceding the expression, indicates that one
           wants to compute a formula and not merely assign a text label to a variable. One
           can also build arbitrarily complex formulas in STATISTICA, using a large number
           of predefined functions (see button  ons Functi   in Figure 2.7).
