ftders function

Student copula cdf/pdf and ders

Derivatives C(u|v), C'_dl(u|v), c(u,v), c'_dl(u,v), c'_u(u,v) for the linking copula

ftders(u, v, cpar, nu, du = FALSE)

Arguments

• u: vector of values in (0,1)
• v: conditioning variable in (0,1)
• cpar: copula parameter in (-1,1)
• nu: degrees of freedom >0
• du: logical value (default = FALSE) for the derivative of the copula density with respect to u

Returns

• out: Matrix of conditional cdf, pdf, and derivatives with respect to parameter

Examples

out = ftders(0.3,0.5,2,25)
