liesInSupport: Generic Function for Testing the Support of a Distribution

Description

The function tests if x lies in the support of the distribution object.

Usage

# S4 method for DiscreteMVDistribution,numeric
liesInSupport(object, x, checkFin = FALSE)
# S4 method for DiscreteMVDistribution,matrix
liesInSupport(object, x, checkFin = FALSE)

Value

logical vector

Arguments

object

object of class "Distribution"

x

numeric vector or matrix

checkFin

logical: in case FALSE, we simply check whether x lies exactly in the numerical support (of finitely many support points); later on we might try to mimick the univariate case more closely in case TRUE, but so far this is not yet used.

Methods

object = "DiscreteMVDistribution", x = "numeric":

does x lie in the support of object.

object = "DiscreteMVDistribution", x = "matrix":

does x lie in the support of object.

Examples

M <- matrix(rpois(30, lambda = 10), ncol = 3)
D1 <- DiscreteMVDistribution(M)
M1 <- rbind(r(D1)(10), matrix(rpois(30, lam = 10), ncol = 3))
liesInSupport(D1, M1)
