Logrank Tests (Freedman)

چکیده
This module allows the sample size and power of the logrank test to be analyzed under the assumption of proportional hazards. Time periods are not stated. Rather, it is assumed that enough time elapses to allow for a reasonable proportion of responses to occur. If you want to study the impact of accrual and follow-up time, you should use the one of the other logrank modules also contained in PASS. The formulas used in this module come from Machin et al. (1997).

Exact and Asymptotic Weighted Logrank Tests for Interval Censored Data: The interval R package.
For right-censored data perhaps the most commonly used tests are weighted logrank tests, such as the logrank and Wilcoxon-type tests. In this paper we review several generalizations of those weighted logrank tests to interval-censored data and present an R package, interval, to implement many of them. The interval package depends on the perm package, also presented here, which performs exact an...
متن کاملComparing Two Survival Time Distributions: An Investigation of Several Weight Functions for the Weighted Logrank Statistic
In survival analysis, it is often of interest to test whether or not two survival time distributions are equal, speci cally in the prescence of censored data. One very popular test statistic utilized in this testing procedure is the weighted logrank statistic. Much attention has been focused on nding exible weight functions to use within the weighted logrank statistic, and we propose yet anothe...
متن کاملWeighted Logrank Permutation Tests for Randomly Right Censored Life Science Data
In biomedical research, weighted logrank tests are frequently applied to compare two samples of randomly right censored survival times. We address the question how to combine a number of weighted logrank statistics to achieve good power of the corresponding survival test for a whole linear space or cone of alternatives, which are given by hazard rates. This leads to a new class of semiparametri...
متن کاملA pretest for using logrank or Wilcoxon in the two-sample problem
In a two-sample location-scalemodelwith censored data, the logrank test is asymptotically efficient when the error distribution is extreme minimum value. On the other hand, the Wilcoxon test is asymptotically efficient when the error distribution is logistic. We propose a pretest for choosing between logrank and Wilcoxon by determining if the error distribution is closer to extrememinimum value...
متن کاملWeighted logrank tests to detect a transient improvement in survivorship.
In investigating whether an intervention has an effect on survival, we exploit the flexibility of weighted logrank tests for constructing optimal tests sensitive to specified patterns of changes in the ratios or differences of the hazards as a function of time. The tests presented seem appropriate if either the intervention on trial imposes changes in life style, such as a diet modification or ...
