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
