Statistical analyses included group by condition repeated-measures ANOVA for metric data, Mann-Whitney U rank and Friedman's rank tests
for nonparametric rank data, Spearman's rho correlations to compare aesthetic rankings and metrics, and linear regression to examine which metric best quantified observers' aesthetic rankings, p < 0.05.
In this paper, we propose a Wilcoxon-type weighted rank test to compare with the existing two Wilcoxon-type rank tests proposed by Mantel  and R.
Peto's  generalized Wilcoxon-type rank tests and propose our weighted rank test.
Wilcoxon-Type Rank Tests for Interval Censored Data
Two-sample Wilcoxon rank test is a well-known method to test whether two samples of exact data come from the same population.
Our Proposed Wilcoxon-Type Weighted Rank Test. To transform an IC data to exact, we first assign each inspection time [x.sub.i] a primary rank [R.sub.i]; for instance, [R.sub.i] = i.
Their topics are chi-squared tests, goodness-of-fit tests based on empirical processes, rank tests
, and other non-parametric tests.
The authors start with the basics of statistics and Bayesian statistics, then cover order statistics, "goodness of fit," rank tests
, relevant designed experiments, categorical data, estimating distribution functions and density, regressions beyond the linear, curve fitting, wavelets, bootstrapping, the Em algorithm, statistical learning, and nonparametric Bayes.
DM patients had a significantly lower overall survival rate than non-DM patients (log rank test, ?
Furthermore, DM patients had a lower free survival rate of cardiovascular event than that of non-DM group (log rank test, ?
2 = 4.222, P = 0.040), and DM with moderately controlled FPG (log rank test, ?
