Group(ContinuousVar,floor,v1,v2,...,ceiling)

Groups the result of the numeric expression in the ContinuousVar into (-infinity, floor), [floor,v1), [v1,v2), [v2,v3)..., [v_n, ceiling), [ceiling,infinity), where floor, v1, v2, ..., v_n, ceiling are numbers satisfying floor < v1 < v2 < ... < v_n < ceiling.

Procedure

To generate a categorical variable, select the Group() in the Function box. Then, click on the

button. The name of the function will appear in the User Defined Variable box. Select a numerical variable in the Variables box and click on the

. The argument variable will appear in the expression. Enter the values floor, v1, v2, ...,ceiling separated with commas and close parentheses.
