In dirmeier/gpR: Gaussian processes in R

Description

Prediction of binomial-distributed random variables using GP regression

Usage

lvgpc(x.train = NULL, c.train = NULL, x.new = NULL, pars = list(var = 1,
  inv.scale = 2, gamma = 2, noise = 0.1, kernel = "gamma.exp"), ...)

Arguments

x.train	vector of independent variables used for training
c.train	vector of dependent variables used for training
x.new	vector of variables for which a response should be predicted
pars	a list containing the hyper-parameters and kernel specifications
...	additional parameters (not specified)

Value

An object of class lvgpc.pred

an lvgpc.pred object

c.predict	the predicted c* values given the lvgpc object
mean.c.predict	the predicted mean c* values given the lvgpc object
mean	the (approximated) posterior mean values
cov	the (approximated) posterior covariance/kernel
call	the function call

Examples

 x.train <- seq(-5, 5, .1)
 c.train <- c(rep(0,25), rep(1, length(x.train)-50), rep(0,25))
 x.new <- rnorm(100)
 pars <- list(var=1, inv.scale=2, gamma=2, noise=.1, kernel="gamma.exp")
 pred <- lvgpc(x.train, c.train, x.new, pars)
