Functions

func ChiSquareStat

func ChiSquareStat(n11 int, n12 int, n21 int, n22 int, yates bool) float64

ChiSquareStat computes the chi-squared test statistic, for a 2x2 contingency table; with optional yates correction. See ChiSquareTest for a p-value.

func ChiSquareTest

func ChiSquareTest(n11 int, n12 int, n21 int, n22 int, yates bool) (stat, pval float64)

ChiSquareTest computes the chi-squared test statistic, for a 2x2 contingency table; with optional yates correction, and then returns the p-value for that test.

func FisherExactTest

func FisherExactTest(n11 int, n12 int, n21 int, n22 int) (probOfCurrentTable, leftp, rightp, twop float64)

FisherExactTest computes Fisher's Exact Test for

contigency tables. Nomenclature:

  n11  n12  | n1_
  n21  n22  | n2_
 -----------+----
  n_1  n_2  | n

Returned values:

probOfCurrentTable = probability of the current table
leftp = the left sided alternative's p-value  (h0: odds-ratio is less than 1)
rightp = the right sided alternative's p-value (h0: odds-ratio is greater than 1)
twop = the two-sided p-value for the h0: odds-ratio is different from 1
