## 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.
