Introduction to Nutrition and Health Research
The Mann-Whitney-Wilcoxon test is a nonparametric alternative to the t test for
two independent samples. It is commonly used where experimenter draws two
random samples from the same parent population, subjects each to a different ...

Diagnostics for Choosing Between Log-rank and
Wilcoxon Tests
Two commonly used tests for comparison of survival curves are the generalized Wilcoxon procedure of Gehan (1965) and Breslow (1970) and the Log-rank test proposed by Mantel (1966) and Cox (1972).

Handbook of Parametric and Nonparametric Statistical ...
In the case of the normal approximation of the Wilcoxon test statistic, the
correction for continuity requires that .5 be subtracted from the absolute value of
the numerator of Equation 6.2. Thus, Equation 6.3 represents the continuity-
corrected ...

An alternative name for the procedure is the Mann-Whitney test, though the Mann
-Whitney test statistic is sometimes expressed in a slightly different form from that
of the Wilcoxon test. The Wilcoxon test procedure is distribution-free because it ...

Computational Methods in Statistics and Econometrics
Hodges and Lehmann (1956) and Chernoff and Savage (1958) showed that the
Wilcoxon test is as powerful as t test under a shift of location parameter for any
population distribution. Remember that the asymptotic relative efficiency of the ...

Deconstructing the Comparative Power of the Independent ...
The Wilcoxon test may be considered the most powerful nonparametric test (
Runyon & Haber, 1991). According to Bradley (1968), “In comparison to other
distribution free statistics, the Wilcoxon test typically either ranks first or, when the
set of ...

Basic Statistics and Pharmaceutical Statistical ...
Wilcoxon Test As mentioned earlier, the traditional comparison of two
independent groups (e.g., t-test) is not appropriate, since survival times are
usually not normally distributed and tend to be positively skewed. Also, censored
data cannot be ...

Modern Mathematical Statistics with Applications
It is therefore relevant to ask (1) how much is lost by using Wilcoxon's test rather
than the pooled ttest when the distributions are normal with equal variances and (
2) how W compares to Tin nonnormal situations. The notion of test efficiency ...

The Wilcoxon test is based on the sum of the ranks in the second sample and can
be computed using the Wilcoxon scores and the test statistic described in
Chapter 1. The Wilcoxon test is not too sensitive to outliers and is the locally most
