摘要
Systematic likelihood inference for frailty models is possible using Lee & Nelder's (1996) hierarchical likelihood. We develop an inferential method for frailty models via hierarchical likelihood, which gives a simple unified framework and a numerically efficient algorithm. Simulations and practical examples are presented to illustrate the new method.
