In ssustat/regbook: Regression Book

Description

The Bivariate Normal Distribution

Usage

dbvnorm(x, mean = c(0, 0), sd = c(1, 1), rho = 0)

Arguments

x	a 2-dimensional vector or a 2 by n matrix
mean	a mean vector
sd	a standard deviation vector
rho	correlation coefficient

Examples

x <- seq(-3,3,length.out=50)
y <- seq(-3,3,length.out=50)
z <- outer(x, y, function(x, y) dbvnorm(cbind(x, y), rho=0.5))
persp(x,y,z,theta=5,phi=20,col="lightblue", expand=0.5, zlab="density")
contour(x,y,z, xlab="x", ylab="y")
