An object returned by the jmodelTM function, inheriting from class jmodelTM and representing a fitted joint model for survival and longitudinal data. Objects of this class have methods for the generic functions AIC, BIC, logLik, print, summary, and vcov.
The following components must be included in a legitimate jmodelTM object.
a list with the estimated parameters. The list is consist of the following components:
the variance-covariance matrix evaluated at the estimated parameter values.
the log-likelihood (the joint likelihood) value.
the estimated values for the random effects
a list containing an image of the jmodelTM call that produced the object.
the number of iterations used in the EM algorithm.
the convergence indicator: if "failure", usually more iterations are required.
the value of the control argument passed to jmodelTM.
the CPU time used to compute the standard error estimates, i.e. the time use to compute the variance-covariance matrix for the parameter estimates.
the total number of repeated measurements for the longitudinal outcome.
the number of sample units.
the censoring indicator: 0 denotes censored survival time; 1 denotes observed survival time.
the transformation parameter used for the survival model.
