Our analysis shows that the Chi-square test has the best power and robustness. Since the POWER-SAGE program can easily run 'virtual' SAGE studies with different combinations of sample size and tag frequency and determine the power for each combination, it can serve as a useful tool for ...
As alike … as grapes in a cluster —Edna Ferber As alike as my finger is to my finger —William Shakespeare As alike as two drops of water —James Miller This simile has become so common that no “As alike” introduction is needed, as illustrated by, “Just like two drops of water,...
test. A post hoc Mann-Whitney test, leveraging phylogenetic information, is conducted for the difference analysis (1). Starting at the first taxonomy level, a Mann-Whitney (or Spearman correlation) test is applied to each taxon’s values, with a predetermined significance level (currentlyp<0.05...
Microsoft Excel has built-in functions to perform some of the calculations needed for statistical significance tests. To perform a chi-squared test, type =CHISQ.TEST(ActualRange, ExpectedRange), where the arguments are arrays of cells. To measure a p-value, use the function =T.TEST. ...
The software has been designed to allow statistical analysis a quick and uncomplicated jobs. AcaStat for MAC and Windows allows data to be extracted from spreadsheets, copy and pasted and dragged and dropped to the tool. The software analysis data, performs t-test, non-parametric test, ...
test this hypothesis, we looked at the concentration of anchors around known SXT cargo hotspots. DIVE’s RAs clustered around the edges of cargo gene hotspots in five SXT ICE variants and a putative hotspot in an unannotated SXT ICE (Fig.2d, Additional file1). Extension of these anchors ...
Suppose we wish to test, say, tensile strength. In a classical sampling scheme, all items are stressed until they break. In the more efficient sequential testing, each item is stressed up to the maximum level that a previous item broke and this yields a sequence of (lower) records. The ...
