class statsmodels.nonparametric.kernel_regression.KernelCensoredReg(endog, exog, var_type, reg_type, bw='cv_ls', censor_val=0, defaults=<statsmodels.nonparametric._kernel_base.EstimatorSettings object>)[source]¶

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.

Parameters:

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.

cv_loo(bw, func)	The cross-validation function with leave-one-out
fit([data_predict])	Returns the marginal effects at the data_predict points.
loo_likelihood()
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.
