Use the ChiSquareGoodnessOfFitTest class
to test whether a sample comes from a specific distribution.
The sample can be supplied as either a vector or
a vector.
The distribution can be specified as a probability distribution (a class that inherits from Distribution)
or a vector. The distribution can be discrete or continuous.
If the sample and distribution are both supplied as a vector, the boundaries
must be identical.
A chi-square test uses binned data. A drawback is that the results of the test depend
on how the data is binned. The test also needs a suffient sample size for the chi-square approximation
to be valid.
The AndersonDarlingTest and OneSampleKolmogorovSmirnovTest tests
are alternatives to the chi-square goodness-of-fit test, but they are valid only for continuous distributions.
