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

karray_like: The maximum number of allowed failures (nonnegative int).
narray_like: The target number of successes (positive int).
yarray_like: The probability of k or fewer failures before n successes (float).

Returns

pndarray: Probability of success in a single event (float) such that nbdtr(k, n, p) = y.
