Comparing survival curves based on medians
BACKGROUND Although some nonparametric methods have been proposed in the literature to test for the equality of median survival times for censored data in medical research, in general they have inflated type I error rates, which make their use limited in practice, especially when the sample sizes are small. METHODS In this paper, we propose a new nonparametric test with a simple test statisti...
متن کاملComparing Survival Curves Using Rank Tests
Survival times of patients can be compared using rank tests in various experimental setups, including the two-sample case and t h e cnse of paired dnta. Attention is focussed on two frequently occurring complications in medical applications: censoring and tail alternatives. A review is given of the author’s recent work on a new and simple class of censored rank test:. Various models for tail nl...
متن کاملIndividual survival curves comparing subjective and observed mortality risks.
We compare individual survival curves constructed from objective (actual mortality) and elicited subjective information (probability of survival to a given target age). We develop a methodology to estimate jointly subjective and objective individual survival curves accounting for rounding on subjective reports of perceived survival. We make use of the long follow-up period in the Health and Ret...
متن کاملComparing survival curves using an easy to interpret statistic.
Here, I describe a statistic for comparing two survival curves that has a clear and obvious meaning and has a long history in biostatistics. Suppose we are comparing survival times associated with two treatments A and B. The statistic operates in such a way that if it takes on the value 0.95, then the interpretation is that a randomly chosen patient treated with A has a 95% chance of surviving ...
متن کاملComparing ROC curves derived from regression models.
In constructing predictive models, investigators frequently assess the incremental value of a predictive marker by comparing the ROC curve generated from the predictive model including the new marker with the ROC curve from the model excluding the new marker. Many commentators have noticed empirically that a test of the two ROC areas often produces a non-significant result when a corresponding ...
