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:

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.

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.
