predict.kdecopula: Prediction method for 'kdecop()' fits

In kdecopula: Kernel Smoothing for Bivariate Copula Densities

Prediction method for kdecop() fits

Description

Predicts the pdf, cdf, or (inverse) h-functions by calling dkdecop(), pkdecop(), or hkdecop().

Usage

## S3 method for class 'kdecopula'
predict(object, newdata, what = "pdf", stable = FALSE, ...)

Arguments

object	an object of class kdecopula.
newdata	evaluation point(s), a length two vector or a matrix with two columns.
what	what to predict, one of c("pdf", "cdf", "hfunc1", "hfunc2", "hinv1", "hinv2").
stable	only used for what = "pdf", see dkdecop().
...	unused.

Value

A numeric vector of predictions.

Examples

data(wdbc)
udat <- apply(wdbc[, -1], 2, function(x) rank(x) / (length(x) + 1))
fit <- kdecop(udat[, 5:6])

all.equal(predict(fit, c(0.1, 0.2)), dkdecop(c(0.1, 0.2), fit))
all.equal(predict(fit, udat, "hfunc1"), hkdecop(udat, fit, cond.var = 1))
