Compute and Recode
The 'Compute' option provides the ability to create user defined variables according to certain pre-defined mathematical and statistical operations. A 'recode' function reassigns the values of existing variables into new values for a new variable.
Note: For the icon to be visible on webview the compute option should be enabled via Configuration tool.refer to webview settings guide for details.
To use the 'Compute' option:
Select the compute icon . This option is disabled when no study is open or if a study has no data.
The system will retrieve any variables you have previously generated or have access to.
If there are no previously generated variables a 'Create' box will appear containing a list of calculation types and the 'Recode' option.
- Using the 'Create' box select a predefined formula, or 'Recode' to begin to compute a new variable.
If user defined variables already exist these can be deleted from the 'Delete' menu.
