bw_t: Bandwidth selection for the transformation kernel estimator
In kdecopula: Kernel Smoothing for Bivariate Copula Densities
bw_t R Documentation
Bandwidth selection for the transformation kernel estimator
Description
The bandwidth is selected by a rule of thumb. It approximately minimizes
the MISE of the Gaussian copula on the transformed domain. The usual normal
reference matrix is multiplied by 1.25 to account for the higher variance
on the copula level.
Usage
bw_t(udata)
Arguments
udata
data.
Details
The formula is
1.25 n^{-1 / 6} \hat{\Sigma}^{1/2},
where \hat{Sigma} is empirical covariance matrix of the transformed
random vector.
Value
A 2 x 2 bandwidth matrix.
