lcrq2: Local Constant Estimator for Conditional Quantile Functions

In Rearrangement: Monotonize Point and Interval Functional Estimates by Rearrangement

Description

Implements the local nonparametric method kernel estimator–with box kernel (default), for conditional quantile functions. This is a modification of Koenker's lprq (from package quantreg).

Usage

lcrq2(x, y, h, xx, tau)

Arguments

x	The conditioning covariate
y	The response variable
h	The bandwidth parameter
xx	The points at which the function is to be estimated
tau	The quantile(s) to be estimated. This should be a list of quantiles if the function estimates the quantile process

Details

The function uses a box kernel.

Value

xx	The design points at which the evaluation occurs
fitted.values	The estimated function values at these design points
