Replicate Cy5/Cy3 ratios for each passing probe were averaged within a method before performing the Cyber t-test [ 26].
The authors proposed the use of a cyber t-test which uses Bayesian statistics to weight the variance of each individual gene with the variance of other genes on the array with similar intensities and also the use of an additional statistic-level normalisation to rectify the problem.
The resulting six-point form, which must be signed by anyone who takes part in the Cyber Sentinel test, requires that all computers the probationer uses be registered with the department and prohibits the use of any other computer.
The new money will allow CISA to offer more support to state election officials and to expand the agency's work on behalf of election officials at the local and county level, he said, offering them services such as cyber penetration testing, vulnerability scans and threat information sharing.
(A cyber attack testing exercise conducted by ENISA last fall also focused on exploring ways to increase collaboration between Member States).
The Cyber-T test [97] was used to determine the significance of the fold ratio change.
In the volcano plot M is plotted as a function of significance, in this case the absolute log transformed p-values from the Cyber-T test.
The Cyber-T test considers the rank order of genes in each biological replicate and uses a Bayesian probabilistic approach to determine the significance of changes based upon the consistency of this rank order between replicates.
For more reliable results, we excluded any subgroup without replication from the comparisons, and we applied the cyber-T test (instead of a standard t-test) for comparative analysis to appropriately account for the small sample size issue common in GEO data sets [19].
For each GEO GDS dataset together with its associated annotation summary, a Python program modified from a previous version [18] was used to extract every subgroup of samples with clearly defined conditions, generate pairs between any two biologically comparable subgroups, and perform cyber-T test for each of these pairs.
