why would survival curves be artificial what is the implications of using only observed data? which scenario would require survival analysis of all data does survival analysis use only observed data how to use survival analysis to understand data what is survival analysis used for why would survival graphs be artificially lower what is the difference between survival curves and survival curves what is the consequence of looking at only observed data?? can an analysis be used to only look at an individual data set? when using survival analysis only observed data what is the impact of survival analysis using just observed data survival curve when only one person is observed which condition would decrease survival probability when examining only the observed data? why do survival curves go so low when you use survival analysis only the observational data is __________. what is survival analysis using only observed data why use only observed data why do survival curves always go below 80% why would survival curves be biased when viewing only the observed data.
