This dataset is a small call center for an anonymous bank (Brown et al., 2005). This dataset provides the exact time of the calls that were connected to the center from January 1 to December 31 in the year 1999. The data are aggregated into time intervals to obtain a data matrix. More precisely, the (i,j)'th element of the data matrix contains the call volume during the jth time interval on day i. This dataset has been analyzed in several prior studies; e.g. Brown et al. (2005), Shen and Huang (2005), Huang et al. (2008), and Maadooliat et al. (2015). Here, the data are aggregated into time intervals 6 minutes.
