Details

When applied to a frailtyHL object summary statistics are producted if the underlying model estimation converged. Otherwise, produces an error message.

Value

It returns a list of summary.frailtyHL object containing the following statistics and tables.

Model

A selected model of log-normal or gamma frailty models.

formula

The formula used in the undelying frailtyHL.

Method

The order of Laplace approximation mord and dord used in the undelying frailtyHL.

FixCoef

A two-dimensional matrix of fixed effects parameter estimates, repective standard errors and t-values.

RandCoef

A two-dimensional matrix of random effects estimates and repective standard errors.

likelihood

Vectors of -2 * likleihood.

iter

Number of iterations used in frailtyHL estimation.

convergence

A text, "converged" if the estimation converged and "did not converge" oterwise.

aic

Three AIC criteria(cAIC, mAIC, rAIC) based on conditional likelihood, marginal likelihood and restricted likelihood
