> The only independent variable is the date and time of birth. Minor nuance. Just sharing this for awareness, not endorsing its validity: When indian astrologers plot a "star chart" / "kundli" / "raasi chakram" of a person -- it is quite literally a snapshot or plot of all major "planets" against the constellations. And this snapshot depends rather precisely on the PLACE of birth as well. (not just the time) The latitude and longitude of the place of birth are starting input variables. There are almanacs and pretty detailed tables of star positions by date and hour, published for use by practitioners, that are used to lookup. The sunrise, sunset times for that place obviously differ by lat/long. And similarly since the "positions" of planets are measured not in absolute terms but against the backdrop of constellations -- so the place of birth also determines for example whether Mars is in Constellation A or whether Jupiter is on the cusp of Constellation B & C. For example you can skim through this book's pages -- that show lat/long and timezone info for places worldwide: https://www.exoticindiaart.com/book/details/ascendant-astrological-tables-ubh655/ https://www.exoticindiaart.com/book/details/ascendant-astrol... These tables go quite deep into accounting for drift of lunar year versus solar year, apparent retrograde motion of planets, precession of axes and correcting for them, etc. The attempt to gather so much data and attempt to do a correlation analysis / modelling on that is fairly ambitious and worthy of acknowledgement IMO.
