KDEMultivariateConditional.pdf(endog_predict=None, exog_predict=None)[source]

Evaluate the probability density function.

Parameters: endog_predict: array_like, optional Evaluation data for the dependent variables. If unspecified, the training data is used. exog_predict: array_like, optional Evaluation data for the independent variables. pdf: array_like The value of the probability density at endog_predict and exog_predict.

Notes

The formula for the conditional probability density is:

with

where is the appropriate kernel for each variable.
