Using copulas with user-defined marginal functions
...vdc(copula = ellipCopula("normal", param = c(rho12, rho13,
rho23),dim = 3, dispstr = "un"),
margins = c("tobit", "tobit", "tobit"),
paramMargins = list(list(beta=beta1,sigma=s1),
list(beta=beta2,sigma=s2), list(beta=beta3,sigma=s3)))
mydmvdc <- dMvdc(y, myMvdc)
Error in eval(expr, envir, enclos) : could not find function "ptobit"
Thanks in advance,
Elisa.
