v
for Farlie-Gumbel-Morgenstern copula C(u, v)
given probability C(u, v)
and u
.
vffgm(C, u, tht)
C |
Probability value of the Farlie-Gumbel-Morgenstern copula. It can be a vector. |
u |
The first variable value of the |
tht |
Copula parameter |
The value of the u
must be grater than C
.
The value of the second variable depending on the first variable and copula probability value.
