Gregory-Loredo Algorithm

No algorithm description given

Computes the Gregory-Loredo algorithm on a list of arrival times This function computes the likelihood of a set of arrival times originating from a periodic process rather than constant rate (Poisson) process (e.g. background noise). based on Gregory, P. C. and Thomas. J. Loredo, 1992, "A New Method For The Detection Of A Periodic Signal Of Unknown Shape And Period" in The Astrophysical Journal, Astrophysical J., 398, p.146 Inputs Tlist (required)- a list of arrival times m_max  (optional, default m_max=12) - number of phase bins w_range (optional, default min(20,N/10)*pi/T, N= number of arrival times, T= max(Tlist)) - frequency range to scan for periodicity ni (optional, default ni=10) - number of bins for numerical integration of the phase from 0:2pi/m parallel (optional, default parallel=False) - parallel execution flag Outputs O_period - odds ratio for periodic process p_period - probability of periodic process (0<=p_period<=1) m_opt - optimal bin size S - spectrum for m_opt w - frequency range of S w_peak - most likely frequency w_mean - mean frequency w_conf - 95% confidence interval of frequency   Other sample inputs:  {"Tlist" : [80,921,2281,5831,6095,7703,8205,8761,11010,11095,14201,22531], "m_max" : 5} {"Tlist" : [80,921,2281,5831,6095,7703,8205,8761,11010,11095,14201,22531],"m_max" :5, "ni" : 20}
