barak.stats.poisson_confidence_interval(conf, nevents)[source]¶

Find the Poisson confidence interval.

Parameters :	conf: float : Confidence level in percent (95, 90, 68.3% or similar). nevents: int : The number of events observed. If 0, then return the 1-sided upper limit.
Returns :	mulo, mhi : floats The two-sided confidence interval such that for mulo, >= observed number of events occurs in fewer than conf% of cases, and for muhi, <= nevents occurs in fewer than conf% of cases.
