Editing Statistical parameter (section)

===Types of parameters===
Parameters are given names appropriate to their roles, including the following:
*[[location parameter]]
*[[Statistical dispersion|dispersion parameter]] or [[scale parameter]]
*[[shape parameter]]

Where a probability distribution has a domain over a set of objects that are themselves probability distributions, the term ''[[concentration parameter]]'' is used for quantities that index how variable the outcomes would be.
Quantities such as [[regression coefficient]]s are statistical parameters in the above sense because they index the family of [[conditional probability distribution]]s that describe how the [[dependent and independent variables|dependent variables]] are related to the independent variables.
