DESCRIPTION: %CHI2_DISCRETIZE performs supervised discretization of a continuous variable based on the values of a categorical variable.
The X^2 algorithm is used to recursively subdivide the values of the continuous variable until there is no improvement in the value of the criterion function (logworth).
SYNTAX: See macro header for definition of variables
EXAMPLE: See initial comments in macro for example of use.
