How can you use “p-values” in a sentence? Here are some example sentences to help you improve your vocabulary:
The presence of statistically significant signals at M/Z values less than 500 was unexpected as some investigators, in their systems, conservatively disregard data beneath M/Z values of 2000 as possible noise [ 12 ] . To further investigate this, we first repeated the calculation of 2-sided Wilcoxon test p-values at each of the 15,154 M/Z values using the entire data set (see Figure 2).
Using the selected gene sets from Table 3and the p-values and fold-change values calculated from the eight normal kidneys and nine CC, we looked for concordance between our results and published reports.
Based on the initial training set, the intensity at each of the consecutive 15,154 M/Z values was first compared using a two-sided Wilcoxon test (see methods) Figure 1shows the pattern of the resulting two-sided Wilcoxon test p-values generated on a training set consisting of 80 cancer patients and 45 controls randomly chosen from the larger data set, with the M/Z values on the x-axis and the negative logarithm (base 10) of the Wilcoxon test p-values on the y-axis.
Disease classifiers of great sensitivity and specificity could be readily constructed by visual inspection and manual binning of M/Z values based on the p-values of the Wilcoxon test combined with classical stepwise discriminant analysis.
As a result, the median scores for some of individual schools are variable, making the ordering inconsistent over testing occasions, which in turn, results in the extreme p-values from the Wilcoxon tests.
