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 that they cannot be manually edited.
This chapter describes the Formula Editor and shows how to build formulas. For more information about each function, see Reference for JMP Functions in Formulas.
