dmvnorm masked by emdbook
I am using curve3d in the emdbook package to graph a gaussian copula density
function generated via the copula package. Unfortunately, it appears that
emdbook masks dmvnorm from the package mvtnorm in a way that prohibits
copula from generating the gaussian copula. (Sounds very confusing!) For
example,

2-parameter MLE problems
Hi all,
Sorry for the re-post, I sent my previous e-mail before it was complete. I
am trying to model seroprevalence using the differential equation: dP/dt =
beta*seronegative*.001*(seropositive)-0.35*(0.999)*(seropositive)-r*seropositive.
I would like to estimate my two parameters, beta and r, using maximum
likelihood methods. I have included my code below:

How to draw the graph of f(x,y) = x * y ?
Dear All,
The function curve() draws the graph of functions from R to R. Is
there some homologous function to curve() to draw functions from R^2
to R?
Thanks in advance,
Paul
