Dear all (not an R question per se, but given that the Real pRo's are all heRe I hope you foRgive) survival analyses assume that censoring is independent of hazard etc (eg, MASS 4th ed, pg. 354). Is there a standard test for this assumption? If there is not, what would you do to examine it empirically? (over and above some thinking about how censoring might be related to baseline factors). Would very much appreciate your thoughts and any pointers you can give Best wishes Paul aRtes ============================================Paul H Artes, PhD Associate Professor & Foundation Scholar in Glaucoma Research Ophthalmology and Visual Sciences, Dalhousie University Rm 2035 West Victoria, 1278 Tower Rd, Halifax, Nova Scotia B3H 2Y5 Canada -- View this message in context: http://www.nabble.com/independence-of-censoring-in-survival-analyses-tp15340503p15340503.html Sent from the R help mailing list archive at Nabble.com.
