The `astropy.stats` package holds statistical functions or algorithms used
in astronomy and astropy.

The current tools are fairly self-contained, and include relevant examples in
their docstrings. For example, see `sigma_clip`.

`scipy.stats`This scipy package contains a variety of useful statistical functions and classes. The functionality in

`astropy.stats`is intended to supplement this,*not*replace it.

This subpackage contains statistical tools provided for or used by Astropy.

While the `scipy.stats` package contains a wide range of statistical
tools, it is a general-purpose package, and is missing some that are
particularly useful to astronomy or are used in an atypical way in
astronomy. This package is intended to provide such functionality, but
*not* to replace `scipy.stats` if its implementation satisfies
astronomers’ needs.
