This dataset consists of simulated monthly segment market shares (SA to SE) corresponding to the 5 segments of a certain brand during 150 consecutive months (01/2003 to 08/2015). The set of explanatory variables was selected by Morais and Thomas-Agnan (2019) as being the most meaningful to explain the segment shares. Names have been simplified.
