LIME Procedure

DISTANCE Statement

DISTANCE <options>;

The DISTANCE statement specifies the options that are related to distance calculation.

You can specify the following options:

EXPONENTIALKERNEL=number

specifies the denominator in the exponential kernel. The default value is based on the input data, as described in the section Distance and Weight Calculation.

IMPUTE=MEAN | NONE | WEIGHTEDMEAN

specifies the method to use for imputing the missing observations. You can specify the following methods:

MEAN: uses the mean to impute missing values of interval variables, and uses the mode to impute missing values of nominal variables.
NONE: does not impute missing values.
WEIGHTEDMEAN: uses the weighted mean to impute missing values of interval variables, and uses the mode to impute missing values of nominal variables.

By default, IMPUTE=NONE.

MIXEDDISTANCEWEIGHT=number

specifies the distance calculation weighting that balances interval and nominal inputs.

By default, MIXEDDISTANCEWEIGHT=1.
