# What is the meaning of Automatic in goodness of fit test?

I can't find what is the distribution corresponding to the default option in:

DistributionFitTest[data, Automatic, "HypothesisTestData"];


Is it N(0,1), uniform?

• Does this answer your question? – Szabolcs Mar 20 '14 at 15:53

By default DistributionFitTest attempts to test fit against the family of normal distributions. To test if the data is standard normal (i.e. N(0,1)) you would use.
DistributionFitTest[data, NormalDistribution[]]

There are examples that show this to be the case in the Properties & Relations section of the documentation for DistributionFitTest.
• @Andy Ross No, first of all ND is bounded on $(-\infty ,\infty )$ and your results as well as BD are bounded on $(0,1)$. Such that you data may be BD. Best to let Mathematica tell you which distribution it most likely is see FindDistribution. That will go through a lot of distributions and select the best ones. – Carl Aug 26 '16 at 21:53
