In hudtorrent/NPreg: Nonparametric Regression

Description

Nadaraya-Watson nonparametric regression at a particular point x0.

Usage

f_nw_0(x, y, x0, h, k1 = dnorm, ...)

Arguments

x	vector with values for the regressor variable;
y	vector with values for the dependent variable;
x0	scalar where the user wants to evaluate the estimator;
h	bandwidth (scalar);
k1	a kernel function;
...	specific parameters for k1.

Value

scalar which is the Nadaraya-Watson estimate at x0.

Examples

n <- 400
x <- runif(n, -1, 1)
e <- rnorm(n, 0, 0.5)
y <- sin(2.5 * pi * x) + e
f_nw_0(x = x, y = y, x0 = 0.5, h = 0.05)
