[2][3][4] Mark McDonough[5] developed the Astrodatabank database work using the astrology birth data collected by Lois Rodden over 40 years of research.
Astrodatabank was later bought by the Swiss company Astrodienst AG, of Alois Treindl, in 2008,[8] and converted into a wiki project and made freely accessible to all.
[14] Researchers have imported Astrodatabank birth chart data into the Statistical Package for the Social Sciences (SPSS) for analysis.
[15][16] Export files of the AstroDienst database were used by the open source Python program TkAstroDb to analyze the contents of the Astrodatabank in a more blunt statistical way.
The ADB researchers concluded that all statistically seen relevant astrological factors were too small to be predictive at the individual level.
And that the large effects found in smaller ADB samples, were statistically seen neglectable when taking into account the 11 degrees of freedom involved with the postulated astrological factors.
[21][22][23][24] Research studies using Astrodatabank to replicate the original results of a successful test conducted by students of statistics class of Lake Forest College has been attempted.
At the suggestion of Marion March, the AA category was included to distinguish between data based on personal memory and that supported by a birth certificate.
[45][46] A DD rating can apply to an entry with multiple claims of different birth data from equally reliable sources.
[47][48] A research article on the cognitive simulation of AstroDatabank records by using the Artificial Intelligence System – AIDOS, was published.
