Nice, but it seems the data for Chapter 4 workshop (callcenter calls) is missing.
It is not in the datasets.zip, nor in the site mentioned in "PUBLIC DATASETS.txt" (http://robjhyndman.c...dldata/data/...)
A me too here. I'm really enjoying the book (thanks Dr. Janert!) and have gotten to the workshop on chapter 4. It looks like the call center data set is missing from the file of them you provided, and is not mentioned as one of the publicly available ones. Can someone give a pointer to this data set, or post it and make it available?
