NWW: Nadaraya-Watson weights.

In sestelo/condsurv: Estimation of the Conditional Survival Function for Ordered Multivariate Failure Time Data

Nadaraya-Watson weights.

Description

Computes the Nadaraya-Watson weights.

Usage

NWW(covariate, x, kernel = "gaussian", bw)

Arguments

covariate	Covariate values for obtaining weights.
x	Covariate value to compute the weight at.
kernel	A character string specifying the desired kernel. See details below for possible options. Defaults to "gaussian" where the gaussian density kernel will be used.
bw	A single numeric value to compute a kernel density bandwidth.

Details

Possible options for argument window are "gaussian", "epanechnikov", "tricube", "boxcar", "triangular", "quartic" or "cosine".

Value

A vector with Nadaraya-Watson weights.
