Also included are topics not usually covered in survival analysis books, such as time-dependent covariates, competing risks, and repeated events. Ordinary least squares regression methods fall short because the time to event is typically not normally distributed, and the model cannot handle censoring, very common in survival data, without modification. 3 Statistical Models for Multilevel Survival Analysis We describe three methods for analysing multilevel survival data: frailty models, which are Cox proportional hazard models with mixed effects, piecewise exponential (PWE) survival models with mixed effects and discrete time survival models with mixed effects. �p���D��@�j+��a����?��]t/l�a��� �������$��&9�ژC'��C?���ɶ6���.K7ę�'�*"�\E���:��Iua,��3���p*T ���{u�'prh1C��!_�RȞw�vy�Q��^�\{w��<0=��Ww���#sQ{] �B�"���աtho͂��Mr�'r�Eɂ �Z�j/9]YK�����!
