Exact test calculator, exact test calculation method, and program

摘要

To efficiently determine the results of Fisher's exact test.SOLUTION: A reference table generation unit 11 stores a reference table, in which the minimum value y(x) and the maximum value y(x) of Y(x) are associated with xfor each element of set T(x, y), in a reference table storage unit 10. Y(x):={y | (x, y)εT, p(f(x, y))≥α} is satisfied, where α is the significance level, f is a whole single-shooting from set S to set T, and fis reverse mapping of the whole single-shooting f. An input unit 12 receives a set of frequencies sεS. The whole single-shooting unit 13 calculates (x, y)←f(s). A mapping unit 14 obtains y(x) and y(x) associated with xfrom the reference table. A determination unit 15 determines whether or not yis greater than or equal to y(x) and less than or equal to y(x). A output unit 16 outputs test results.SELECTED DRAWING: Figure 1
