problem understanding the result of pnorm2d()
...,
I am using the fMultivar package for calculating probabilities of bivariate normal distribution. I use the manual's example to understand what is going on, but let's take it for smaller dimensions of x and y:
## Bivariate Normal Density:
x = c(0.3,10)
y = c(-10,0.2)
X = grid2d(x,y)
z = pnorm2d(X$x, X$y, rho = 0.5)
Z = list(x = x, y = y, z = matrix(z, ncol = length(x)))
persp(Z, theta = -40, phi = 30, col = "steelblue")
What does the grid2d() command do?
In the Z- result in the matrix, I really cannot figure out where the 4 probabilities are referring to. Can anyone enlighten...
