I believe so. However, my primary focus for 19 years has been on financial markets.
I did some preliminary analysis in a geo-physics study concerning geyser frequencies and found these frequencies to correlate with gravitational fluctuations.
Other areas I researched included: criminal behavior; live births; automobile accidents; administering cancer medications; psychology, North Atlantic ice flows, rain and drought cycles, hurricane frequencies, individual physical performance; and, retail sales performance. I compared these statistics to gravitational fluctuations and in every case the studies showed correlation and good utility.
