Working with numeric variables

Desktop User Guides > Professional > Table scripting > Getting started > Working with numeric variables

Sample script file: NumericVariables.mrs

The variables in the preceding examples are categorical variables. However, you can also use numeric variables if the variable has an axis specification defined for it in the metadata, or if you create an axis specification that summarizes the variable or bands it into categories.

Table showing visits by gender, with visits banded into two categories and additional mean row

For example, the visits variable in the Museum data set is a numeric variable that records the number of times respondents have visited the museum before. This example creates an axis specification for this variable, containing two elements that use expressions to group the numeric values into categories and a special statistical element to show the mean value.

TableDoc.Tables.AddNew("Table1", _
   "visits{visits1 '1 to 10' expression('visits > 0 And visits < 11'), "_
   + "visits2 'More than 10' expression('visits > 10'), " + _
   "mean 'Mean' mean(visits)}" + _
   "* gender", "Number of visits by Gender")

Here is the table produced by the script:

When you use an expression element to band a numeric variable, you can use any expression that is supported by the UNICOM Intelligence Data Model, including functions in the UNICOM Intelligence Function Library.

For information about the functions that come with the UNICOM Intelligence Data Model, see UNICOM Intelligence Function Library
