* Hi, ** I'm dealing with wind data and I'd like to model their** distribution.** 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. **An alternative in such cases (i.e., when marginals are available but** the** joint is difficult to postulate) is to use copulas, which can** construct* * multivariate distributions from univariate marginals. Therefore, if anyone has an idea of how to do whether joint distribution or copula forwind data in R,Please, contact with me.* *Best Regards * *Nasr * [[alternative HTML version deleted]]
