Abstract:
|
We first develop parametric modeling on clustered multivariate current-status survival data with frailty. Both inter-subjects correlations at the same state and intra-correlations between states are modeled by using multivariate exponential frailty distribution. Monte Carlo version of the EM algorithm and Newton-Raphson algorithm are used for parameter estimation. The model and computing method are then applied to analyze breeding success of the common raven.
