PROPHET StatGuide: Distribution Tests -- Test whether the observed
distribution for the sample conforms to the hypothesized
population distribution
- Normal Distribution
(test whether the distribution
from which the data were sampled
is a normal [Gaussian] distribution.)
- Uniform Distribution
(test whether the distribution from which the data were sampled
is a uniform distribution.)
- t Distribution
(test whether the distribution from which the data were sampled
is a Student's t distribution.)
- F Distribution
(test whether the distribution from which the data were sampled
is an F distribution.)
- Chi-square Distribution
(test whether the distribution from which the data were sampled
is a chi-square distribution.)
- Goodness of Fit [Chi-square]
(test whether the distribution from which the nominal
counted data were drawn agrees with a specified distribution
by comparing the observed and expected frequency counts.)
The full version of StatGuide for distribution tests will be available
in a future release. In the meantime, to properly analyze and interpret results
of distribution tests, you should be familiar with the following terms
and concepts:
If you are not familiar with these terms and concepts, you are advised to
consult with a statistician. Failure to understand and properly apply
distribution tests may result in drawing erroneous conclusions from your
data. Additionally, you may want to consult the following references:
