The dataset consists of quarterly sales of a well-known brand of a particular article of clothing
at stores of a large national retailer. The left column contains the values (number of articles sold per quarter) and the second column contains frequencies (number of quarters).
Even at the quarterly level, sales of a particular clothing brand, style, color, and size can be meager. In may quarters, there are no units sold at all. An example of a clothing article at this level of specificity is men's Gold Toe Windsor Wool Midcalf black socks
(which come in only one size). The following sales data are for a clothing article other than socks, but it is of the same level of specificity. Retailers use this type of sales data to plan their inventory/order quantities.
The data can be found at http://www.stat.cmu.edu/COM-Poisson/Sales-data.html
