barak.stats.binomial_confidence_interval¶
- barak.stats.binomial_confidence_interval(conf, ntrial, nsuccess)[source]¶
Find the binomial confidence level.
Parameters : conf: float :
Confidence level in percent (95, 90, 68.3% or similar).
ntrial: int :
The number of trials.
nsuccess: int :
The number of successes from the trials. If 0, then return the 1-sided upper limit.
Returns : plo, phi : floats
The two-sided confidence interval: probabilities such that >= observed number of successes occurs in fewer than conf% of cases (plo), and prob such that <= number of success occurs in fewer than conf% of cases (phi).
