Local variables are most often used with Assignment functions, which can assign expressions to local variables that are used in a complex equation. (For details, see Assignment Functions in Formula Functions Reference.) This technique can sometimes simplify building an equation and improve the efficiency of its evaluation.
3.

Click the menu on the formula element browser and select Local Variables from the formula element browser menu.

4.

Click New Local Variable.

5.

Type a name for the local variable. By default, local variables have the names t0, t1, and so on, and have missing values.

7.

2.

Click the local variable name in the Local Variables list. It appears in the formula as a bold italic term.

Note: Another way to create local variables is to use the button on the Formula Editor keypad, which automatically creates and displays local variables and places a semicolon after it. See Add Operators, for details.
See Use Local Variables in a Formula, for an example of referencing local variables in a formula.

4.

Click New Parameter.

5.

Type a name for the parameter. By default, parameters have the names b0, b1, and so on, and have missing values.

7.

(Optional) To add several parameters (one for each level of a categorical variable, for example) at once, select Expand into categories, selecting column. Then select the column for which you want to expand the parameter.

8.

Click OK.

9.

2.

Click the parameter name in the Parameters list. The parameter appears in the formula as bold type.
