Description

Pearson's chi squared test.

Synopsis

Documentation

chi2test #

Arguments

:: (Vector v (Int, Double), Vector v Double)
=> Double	p-value
-> Int	Number of additional degrees of freedom. One degree of freedom is due to the fact that the are N observation in total and accounted for automatically.
-> v (Int, Double)	Observation and expectation.
-> TestResult

Generic form of Pearson chi squared tests for binned data. Data sample is supplied in form of tuples (observed quantity, expected number of events). Both must be positive.

Data types

data TestType #

Test type. Exact meaning depends on a specific test. But generally it's tested whether some statistics is too big (small) for OneTailed or whether it too big or too small for TwoTailed

Constructors

OneTailed
TwoTailed
