Information sources
Astrology and statistics

This page lists the information sources I found to gather documentation about statistical tests on astrology. I am looking in two main directions :
  • Gather informations about the history of these tests.
  • Find raw data that can be used to restore the original tests.

Web sites

Here are listed the main sites where I found original information.
