Inference Based on Ranks with Tied Failure Time or Grouped Survival Data

Journal Article

Abstract

Scores for the analysis of distinct failure time data using ranks are modified to deal with tied failure times or grouped data. Approximate techniques for inference for regression parameters are considered for ‘proportional odds’ and ‘proportional hazards’ survival data involving tied failures or grouped data. An illustration is given involving a two sample problem.
