bivariate normal cdf and rho
Suppose F(x, y; rho) is the cdf of a bivariate normal distribution, with
standardized marginals and correlation parameter rho. For any fixed x and
y, I wonder if F(x, y; rho) is a monotone increasing function of rho,
i.e., there is a 1 to 1 map from rho to F(x, y; rho).
I explored it using the function pmvnorm in pac...

Greek in text()
I have gone over the examples and can't figure this out:
rho<-.77
text(x=.05,y=.5,paste(expression(rho),rho))
I was hoping to get this to print a Greek rho with 0.77 beside it.
Instead I get: rho 0.77 (i.e. Roman lettering)
The help on expression() is quite opaque so I don't understand how it
works.
Thanks for any help.

a question about d F(x, y; rho) / d rho = f(x, y; rho)
Hello,
My name is IKJIN LEE and I am studying in University of Iowa.
Recently, I have been trying to prove the fact d F(x, y; rho) / d rho =
f(x, y; rho),
but I could not. In the mean time, I found that Professor S. Le Cessie
from Netherlands kindly gave you an elegant proof of
d F(x, y; rho) / d rho = f(x, y; rho).
If you don't mind, can I know the proof?
