The posts just keep on rolling about rolling averages

The technique of averaging figures for set periods of time, such as for the previous three months, produces what is called a rolling average. Several posts on this blog have applied that methodology (See my post of Jan. 6, 2006: rolling averages help detect longer-term trends; March 9, 2007: rolling forecasts for budgets; Oct. 29, 2007: base discount level on rolling average; Jan. 13, 2008: sizeable matters can use rolling forecasts; Jan. 21, 2009: quarterly updates of budget at JDS Uniphase; Nov. 21, 2008: performance against budget, on rolling basis, determines assignments of work; May 3, 2009: burn rates expressed in rolling terms; and Aug. 11, 2009: just-in-time budget method.).
