Wilcoxon-signed rank testComparing the means of two groups is the most frequently used hypothesis test, and is known as the "Student" t-test. There are different versions for paired and unpaired data. If the requirements for the test are not met, alternative nonparametric tests such as the ...
two sample testsAspin-Welch testFisher-Behrens problem.The usual t-test for testing that two samples come from a common normal population cannot be used to test H0: 1 = 2 for two samples drawn respectively from normal populations if . Many solutions to this problem, known as the two ...

This study examines the relative effectiveness of two means of analyzing the pre-test/post-test control group experimental design. Samples were randomly drawn from a standardized normal population and assigned to one of the four cells of the design. A set of experimental differences were induced in...
was studied by setting up different experimental conditions to test the generality and practicality of the algorithm. In addition, the advantages and disadvantages of the two algorithms were compared with the aim of finding a more suitable method for estimating the number of wheat ears in the ...
No adjustment is made to the error rate for multiple comparisons. Used for pairwise comparison. This test does not control the overall probability of rejecting the hypotheses that some pairs of means are different, while in fact they are equal. LSD. 用途t测试成对地执行所有比较在小组手段之间。
univariate counterparts [5,8,9], unless all traits are highly correlated [9,10]. Second, the meta-analysis of summary statistics enables to combine results from single trait GWAS, which means that the analyses can be carried out with different sets of individuals for each trait [1,11,12,...
