Parametric Model Functions
“Reference Columns and Table Variables” on page 206 in the “Formula Editor” chapter). Then use that
variable as the left-hand argument of the assignment function.
= (assign) Puts the value of b into a. For example (a=b).
+= (add to) Adds the value of b to a and puts the result back into a. For example, a+=b.
-= (subtract to) Subtracts the value of b and puts the result back into a. For example, a–=b.
*= (multiply to) Multiplies b with a and puts the result back into a. For example, a*=b.
/= (divide to) Divides b into a and puts the result back into a. For example, a/=b.
++ (post increment) Adds one (1) to a, in place, so that a++. For example, if the initial value of a is 4, the
expression a++ changes a to 5.
-- (post decrement) Subtracts one (1) from a, in place, so that a– – . For example, if the initial value of a
is 4, the expression a– – changes a to 3.
Parametric Model Functions
This category is a short cut to create three parametric models that are linear functions of set of
window-selected columns.
Linear Model, Interactions Model, Full Quadratic Model
Selecting each of these opens a column selection box that lets you select one or more columns to be included
in the model. The function then creates and populates the chosen model.
Finance Functions
Lets you create formulas to calculate principal payments, interest rate, rate of return, and so on.
Double Declining Balance
Returns the depreciation of an asset for a specified period of time. The function uses the double-declining
balance method or some other depreciation factor.
Future Value
Returns the future value of an investment that is based on periodic, constant payments and a constant
interest rate.
Interest Payment
Returns the interest payment for a given period for an investment that is based on periodic, constant
payments and a constant interest rate.
