Functions Included
Lets you construct a Linear, Interactions, or Full Quadratic model for
columns that you choose. After choosing the type of model, a window appears
that lets you select the variables from which to construct the model. Hold the
CTRL key and click to select more than one. See “Parametric Model
Functions” on page 442 in the “Formula Functions Reference” appendix.
Lets you create formulas to calculate principal payments, interest rate, rate of
return, and so on. See “Finance Functions” on page 442 in the “Formula
Functions Reference” appendix.
Order Expressions in Formulas
As you build a formula, keep in mind that all functions have an order of precedence shown in the following
table, where level one is the highest order of precedence. Expressions with a high order of precedence are
evaluated before those at lower levels. When an expression has operators of equal precedence, it is evaluated
from left to right. You can use parentheses to override other precedence rules when necessary because any
expression within parentheses is always evaluated first. Terms have no order of precedence because they
cannot be evaluated further. Table 7.3 shows the first six levels of the order of precedence.
