scipy.special.nbdtri¶
- scipy.special.nbdtri(k, n, y) = <ufunc 'nbdtri'>¶
Inverse of nbdtr vs p.
Returns the inverse with respect to the parameter p of y = nbdtr(k, n, p), the negative binomial cumulative distribution function.
Parameters: k : array_like
The maximum number of allowed failures (nonnegative int).
n : array_like
The target number of successes (positive int).
y : array_like
The probability of k or fewer failures before n successes (float).
Returns: p : ndarray
Probability of success in a single event (float) such that nbdtr(k, n, p) = y.
