Multivariate vector field kernel estimator

See references for details.

Usage

MVKE(d, h = 0.2, kernel = c("exp", "Gaussian"))

Arguments

d

The dataset. Should be a matrix or a data frame, with each row representing a random vector.

h

The bandwidth for the kernel estimator.

kernel

The type of kernel estimator used. "exp" by default (exp()), and if "Gaussian" then stats::dnorm() will be used.

Value

A function(x), which then returns the \(\mu\) and \(a\) estimators at the position \(x\).
