The sample data table Diesel Ship Engines.jmp contains data on engine repair times for two ships (Grampus4 and Halfbeak4) that have been in service for an extended period of time. See Meeker and Escobar (1998). You want to examine the progression of repairs and gain a sense of how often repairs might need to be done in the future. These observations can help you decide when an engine should be taken out of service.
