Editing Multidimensional analysis (section)

==Higher dimensions==
In many disciplines, two-dimensional data sets are also called [[panel data]].<ref>{{cite book |first=G.S. |last=Maddala |title=Introduction to Econometrics |publisher=Wiley |year=2001 |isbn=0471497282 |edition=3rd}}</ref> While, strictly speaking, two- and higher-dimensional data sets are "multi-dimensional", the term "multidimensional" tends to be applied only to data sets with three or more dimensions.<ref>{{cite journal |last=Davies |first=A. |first2=K. |last2=Lahiri |title=A new framework for testing rationality and measuring aggregate shocks using panel data |journal=Journal of Econometrics |volume=68 |issue=1 |pages=205–227 |year=1995 |doi=10.1016/0304-4076(94)01649-K }}</ref> For example, some forecast data sets provide forecasts for multiple target periods, conducted by multiple forecasters, and made at multiple horizons. The three dimensions provide more information than can be gleaned from two-dimensional panel data sets.
