init(self, data, p_null=0.05)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

p_null (float in (0,1)) - threshold at which to reject null hypothesis of conditional independence

Overrides: object.__init__

separates(self, x, y, s)

source code

Tests if x is separated from y given the separator s. Test rejects this hypothesis at p_null.

Returns:: True if hypothesis is not rejected
Overrides: HypotheticalSeparator.separates: (inherited documentation)

confidence(self, x, y, s)

source code

Returns the confidence in the hypothesis x_|_y|s. Higher return value should imply a higher confidence.

Overrides: HypotheticalSeparator.confidence: (inherited documentation)

test_independ(self, x, y, s)

source code

Test if x _|_ y | s. returns (p,s,d) where p is the probability of the available data, given the null hypothesis of independence, s is the test statistic, and d is the number of degrees of freedom in the available data for this test.
