# scipy.stats.rv_discrete.interval

`rv_discrete.``interval`(alpha, *args, **kwds)

  Confidence interval with equal areas around the median.

  Parameters: | alpha : array_like of float Probability that an rv will be drawn from the returned range. Each value should be in the range [0, 1]. arg1, arg2, ... : array_like The shape parameter(s) for the distribution (see docstring of the instance object for more information). loc : array_like, optional location parameter, Default is 0. scale : array_like, optional scale parameter, Default is 1.
  Returns: | a, b : ndarray of float end-points of range that contain `100 * alpha %` of the rv’s possible values.
