Formula Editor
Construct Formulas
Use the JMP Formula Editor to create a column whose values are computed by a formula and store that
formula as part of a column’s information. Formulas can be simple assignments of numeric, character, or
row state constants, or they can contain complex evaluations based on conditional clauses. You can examine
or change the formula at any time.
The Formula Editor window operates like a calculator with buttons, displays, and a list of functions.
Figure 7.1 The Formula Editor
Formulas are an integral part of a data table for the following reasons:
• They are stored as part of a column’s information when you save the data table.
• You can examine or change them at any time by opening the Formula Editor.
• Their values can be linked to, or dependent on, the values in other columns. Their values are
automatically recomputed whenever you edit the values in the columns to which the formula is linked.
• Their values are locked in the data table so they cannot be manually edited.
This chapter describes the Formula Editor and shows how to build formulas. For details about each
function, see the “Formula Functions Reference” chapter on page 395.
