loglike.gumbel.unconstrained: Log-likelihood function for the Gumbel copula.

In depCensoring: Statistical Methods for Survival Data with Dependent Censoring

Log-likelihood function for the Gumbel copula.

Description

This likelihood function is maximized to estimate the model parameters under the Gumbel copula.

Usage

loglike.gumbel.unconstrained(para, Y, Delta, Dist.T, Dist.C)

Arguments

para	Estimated parameter values/initial values.
Y	Follow-up time.
Delta	Censoring indicator.
Dist.T	The distribution to be used for the survival time T. This argument can take one of the values from c("lnorm", "weibull") and has to be the same as Dist.C.
Dist.C	The distribution to be used for the censoring time C. This argument can take one of the values from c("lnorm", "weibull") and has to be the same as Dist.T.

Value

Maximized log-likelihood value.
