The
data is for weekly sales of an end cap promotional item in the dry goods
department at a Wal*Mart store in the Northeast. Peak values, I.e. spikes, occur at promotional periods. Week 1 is the first week of February
2003. To show continuity, week 1 of
2004 is represented as week 53 since week 52 represents the end of fiscal
2003 and week 53 is the start of the 2004 fiscal year. Dollar values are
adjusted in order to disguise true sales figures, but trends in the data are
retained for analysis puposes. |
