Does anybody have suggestions on how to de-normalize Google Trends data? The site says that their trends are made with the following metric:
The numbers on the graph reflect how many searches have been done for a particular term, relative to the total number of searches done on Google over time. They don't represent absolute search volume numbers, because the data is normalized and presented on a scale from 0-100. Each point on the graph is divided by the highest point and multiplied by 100. When we don't have enough data, 0 is shown
I've been trying to work backwards from there but realized I need the peak value for each search query, which I don't have. Any thoughts appreciated.
Here's an example Google Trends search: http://www.google.com/trends/explore#q=stack%20exchange&cmpt=q&tz=
