cont.jexp: Expected Value of Two Continuous Random Variables

In jhk0530/Rstat: Basic Statistical Methods in R

Description

Joint pdf and Expected Value of Two Continuous Random Variables

Usage

cont.jexp(FUN, lo1 = -Inf, up1 = Inf, lo2 = -Inf, up2 = Inf, dig = 4, prt = "exp")

Arguments

FUN	Continuous joint probability density function
lo1	Lower limit of X, Default: -Inf
up1	Upper limit of X, Default: Inf
lo2	Lower limit of Y, Default: -Inf
up2	Upper limit of Y, Default: Inf
dig	Number of digits below the decimal point, Default: 4
prt	Option for detailed output in c("", "exp", "cov", "cor"), Default: ”

Value

list(Ex=E(X), Dx=D(X), Ey=E(Y), Dy=D(Y), Vxy=Cov(X,Y), Cxy=Corr(X,Y))

Examples

pdf <- function(x, y) 0.5 * (x + 3 * y) * (x > 0 & x < 1) * (y > 0 & y < 1)
cont.jexp(pdf, prt = "cor")
