Business Analytics: Data Analysis and Decision Making Hardcover – January 1, 2014

I'm Japanese. I purchased the subject book a week ago. I tried several time to download the data files which are used in the text book. I could no get in touch to even download page of this data files. Unless I cannot use this data files, the value of this text book is none for me. I paid Japanese yen of 15,336 or equivalent to US$ 150. I wasted a big money. I'm very disappointed. If does somebody know how to solve my problem, please help me. I'll appreciate it very much.
