Method Details

compute

public static double compute(int A,
 int B,
 int C,
 int D)

Compute the probability for a specific tail for the table {{A, B}, {C, D}}, that is, towards large A and D and small B and C. (This was factored out of the old Haplo Analyzer and is used when computing association).

Parameters:

A - the a

B - the b

C - the c

D - the d

Returns:

the p-value

computeOneTailed

public static double computeOneTailed(int A,
 int B,
 int C,
 int D)

Compute the one-tailed probability for the table {{A, B}, {C, D}}.

Parameters:

A - the a

B - the b

C - the c

D - the d

Returns:

the p-value

computeTwoTailed

public static double computeTwoTailed(int A,
 int B,
 int C,
 int D)

Compute the two-tailed probability for the table {{A, B}, {C, D}}.

Parameters:

A - the a

B - the b

C - the c

D - the d

Returns:

the p-value
