Normal reference rule for estimating bandwidths

Description

The simplest method for estimating bandwidths, based on normal density assumption.

Usage

nrr(data_x, logband = TRUE)

Arguments

data_x

Regressors

logband

When logband=TRUE, log bandwidths are given. When logband=FALSE, bandwidths are given.

Value

Bandwidths.
