Calculations

Select menu: Data | Calculations

Use this to create an arithmetic or logical expression for evaluation by Genstat. The expression is displayed at the top of the menu and can be constructed step by step by combining data structures and operators. You can use brackets to control the order of evaluation when required. You can also type directly into the expression field.

After you have imported your data, from the menu select
Data | Calculations.

Available data

Lists data structures of the types requested. Double-click a name to copy it into the expression being formed.

History button

The history button opens the Calculate History dialog which allows you to reuse a previous calculation.

Save result in

Specifies a data structure to contain the result of the expression. If this structure already exists you should ensure it is the appropriate type to store the result. For example, if you specify a matrix expression M1*+M2 to be stored in M3, M3 must either not exist or be a matrix of the appropriate dimensions.

Functions

Enables you to insert a function into the expression.

Keypad

Use the keypad to enter operators into the expression being formed. Click the keypad to view an explanation of each of the functions.

You can also type the corresponding text directly into the expression, but note that the logical operators (and, eqs, or, nes, not, is, in, ni, eor, isnt) must be delimited by dots (for example .and.).

Display in output

Lets you display the resultant values in the Output window.

Display in spreadsheet

Lets you display the results in a spreadsheet. You can select the sheet from the list of current open spreadsheets or request a new spreadsheet is created. Note: the number of rows of the spreadsheet must match the length of the results formed by the calculation, otherwise a new sheet will be used.
