# RegularEvents¶

class astropy.stats.RegularEvents(dt, p0=0.05, gamma=None, ncp_prior=None)[source]

Bayesian blocks fitness for regular events

This is for data which has a fundamental “tick” length, so that all measured values are multiples of this tick length. In each tick, there are either zero or one counts.

Parameters: dt : float tick rate for data p0 : float (optional) False alarm probability, used to compute the prior on $$N_{\rm blocks}$$ (see eq. 21 of Scargle 2012). If gamma is specified, p0 is ignored. ncp_prior : float (optional) If specified, use the value of ncp_prior to compute the prior as above, using the definition $${\tt ncp\_prior} = -\ln({\tt gamma})$$. If ncp_prior is specified, gamma and p0 are ignored.
