ASTROYANA RESEARCH
Research
Astroyana publishes reproducible studies generated with its astrology engine. The studies use synthetic charts, not customer data, to measure dosha prevalence, compatibility thresholds, birth-time sensitivity and other calculation behaviour. The figures describe how the system behaves and do not make claims about anyone’s life.
See how the samples and calculations are defined. Read the full methodology.
