This mode is used to perform univariate feature selection with Kendall tau rank correlation coefficient. The value of the feature is correlated with the label (converted to 0/1). If the absolute value of Kendall tau is more than a threshold (indicating positive or negative correlation), then the feature is selected as an informative biomarker. It is implemented by org.bdval.DiscoverWithKendallTau.

Mode Parameters

The following options are available in this mode

Flag Arguments Required Description
--ratio ratio no The Kendall tau value used as threshold. Default Tau > = 0.5.
--output-gene-list n/a no Write features to the output in the tissueinfo gene list format.
--report-max-probes report-max-probes no Restrict output to the top ranked probes. This option works in conjunction with the ratio and can further restrict the output.
