Maximum likelihood estimate of bivariate vonmises-weibulldistribution
...eekend to understand every bit but your code will prove very
useful.
Cheers,

look at the following code:
library(copula)
par(mfrow = c(2, 2))
x <- mvdc(normalCopula(sin(0.5 * pi /2)), c("norm", "norm"),
list(list(mean = 0, sd = 1), list(mean = 0, sd = 1))) contour(x, dmvdc,
xlim = c(-2.7, 2.7), ylim = c(-2.7, 2.7))
x <- mvdc(frankCopula(5.736...

I bet your friend was really angling for that.

my problem actually arised with fitting the data to the weibulldistribution,
where it is hard to see, if the proposed parameterestimates make sense.

Maximum likelihood estimate of bivariate vonmises-weibull distribution
Hi,
I'm dealing with wind data and I'd like to model their distribution in
order to simulate data to fill-in missing values. Wind direction are
typically following a vonmises distribution and wind speeds follow a
weibull distribution. I'd like to build a joint distribution of
directions and speeds as a VonMises-Weibull bivariate distribution.
First is this a stupid question? I'm
