[edit] Description
- Brief description of what it is and what its used for.
- Mathematical formula
- Link to a Wikipedia article on it.
[edit] Usages
Describe in detail here data sets and purposes on which it is most useful. Describe also data sets for which it may give misleading results.
[edit] Distributions
- Include standard values for common distributions, if they exist. For example, a normal distribution always has a skew and kurtosis of zero.
- Include standard error for normal distribution, and for other distributions also if possible.
- Sampling distribution.
[edit] Calculation
Include any alternative methods of calculation, especially for large data sets, or when other measures have already been calculated.
(An example: once you have the count, sum, sum of squares, cubes and fourth powers for a data set, you can then use these to easily calculate the Mean, Std. Dev, Skew and Kurtosis, rather than having to go through the entire dataset multiple times calculating differences.)
[edit] Software
Include how it is accessed in common statistical packages, if known. Can also provide links to source code samples for calculating it, etc.
