public class TBinaryTestTable
Defines binary test table structure.
Defines 2x2 binary test table structure. An important task in diagnostic is to measure the accuracy of a diagnostic test.

The results of such a study can be displayed in a 2-by-2 table in which the true condition is shown as the rows and the diagnostic test result is shown as the columns.
