Is Astrology superstition?

To the extent that it lacks scientific rigour and the ability of being validated by scientific observation and experiment,it will continue to be in the domain of superstition.However,purely on a statistical basis I have seen it working.Good astrologers have used predictive analytic tools in their own ways(akin to regression models) to mine large amount of horoscopic data to come out with trends and patterns which do work many times in predicting events.Astrologers can be likened to the technical analysts of the stock market who generally have a better success rate than fundamental analysts.Eventhough predictive success can be coincidental in many cases,it can certainly help people broadly know the shape of things to come to prevent impending disasters if any.
