bvn.plot: make plots of bivariate normal distributions
Description
The function uses functions from lattice and mvtnorm to make wireframe plots of bivariate normal distributions. Remember that the covariance must be less than the product of the marginal standard deviations (square roots of the diaganol elements).Usage
bvn.plot(mu = c(0, 0), cv = 0, vr = c(1, 1), res = 0.3, ...)
Arguments
mu
A vector cotanining the joint distribution means.
cv
A number, indicating the covariance of the two variables.
vr
The diagonal elements in the variance covariance matrix.
res
Plot resolution. Smaller valaues create a more detailed wireframe plot.
