Multivariate Gaussian cumulated density function

Description

Calculate the Multivariate Gaussian cumulated density function

Usage

util.mvncdf(lower, upper, varcov = NA, mean = NA, 
maxpts = NA, abseps = 1e-06, releps = 1e-06)

Arguments

lower	Array of lower integration limits. If not defined, the lower limit must be set to -Inf.
upper	Array of upper integration limits. If not defined, the upper limit must be set to Inf.
varcov	Variance-covariance matrix of the Gaussian variables. If not defined, it is defaulted to the unit correlation matrix.
mean	Array of the Gaussian means. If not defined, the Gaussian are considered as centered.
maxpts	Maximum number of function values allowed
abseps	Absolute error tolerance
releps	Relative error tolerance

Value

Returns the value of the multivariate Gaussian cumulated density.
