Nonparametric censored regression.

Calculates the condtional mean E[y|X] where y = g(X) + e, where y is left-censored. Left censored variable Y is defined as Y = min {Y', L} where L is the value at which Y is censored and Y' is the true value of the variable.


endog: list with one element which is array_like :

This is the dependent variable.

exog: list :

The training data for the independent variable(s) Each element in the list is a separate variable

dep_type: str :

The type of the dependent variable(s) c: Continuous u: Unordered (Discrete) o: Ordered (Discrete)

reg_type: str :

Type of regression estimator lc: Local Constant Estimator ll: Local Linear Estimator

bw: array_like :

Either a user-specified bandwidth or the method for bandwidth selection. cv_ls: cross-validaton least squares aic: AIC Hurvich Estimator

censor_val: float :

Value at which the dependent variable is censored

defaults: EstimatorSettings instance, optional :

The default values for the efficient bandwidth estimation

Attributes :

——— :

bw: array_like :

The bandwidth parameters

*Methods* :

r-squared : calculates the R-Squared coefficient for the model.

fit : calculates the conditional mean and marginal effects.


aic_hurvich(bw[, func]) Computes the AIC Hurvich criteria for the estimation of the bandwidth.
cv_loo(bw, func) The cross-validation function with leave-one-out
fit([data_predict]) Returns the marginal effects at the data_predict points.
r_squared() Returns the R-Squared for the nonparametric regression.
sig_test(var_pos[, nboot, nested_res, pivot]) Significance test for the variables in the regression.
