Chapter 9 Survival Analysis and EM !
Life-table estimates and KM estimates!
Log-rank test for equal hazards at ALL event times!
Crucial Implications!
❖ Assume successive conditional independence, given the n_k values
Derivation of Partial Likelihood!
❖ Mu1 and sigma1 can be determined from raw data; So they are fixed in EM
❖ EM convergence can be slow
Self-consistency behind EM!
All are rank-based!
