dncs | R Documentation |
This function computes the density of the non-central squared copula (ncs) associated with a one-parameter copula with parameter cpar, and parameters a1, a2 >0 .
dncs(data, family, rotation = 0, par)
data |
Matrix (x,y) of size n x 2 |
family |
Copula family: "ncs-gaussian", "ncs-clayton", "ncs-frank", "ncs-gumbel", "ncs-joe", "ncs-plackett”. |
rotation |
Rotation: 0 (default value), 90, 180, or 270. |
par |
vector of copula parameter and non-centrality parameter a1,a2 >0 |
