# scipy.special.bdtrc¶

scipy.special.bdtrc(k, n, p) = <ufunc 'bdtrc'>

Binomial distribution survival function.

Sum of the terms k + 1 through n of the binomial probability density,

$\mathrm{bdtrc}(k, n, p) = \sum_{j=k+1}^n {{n}\choose{j}} p^j (1-p)^{n-j}$
Parameters: k : array_like Number of successes (int). n : array_like Number of events (int) p : array_like Probability of success in a single event. y : ndarray Probability of k + 1 or more successes in n independent events with success probabilities of p.

Notes

The terms are not summed directly; instead the regularized incomplete beta function is employed, according to the formula,

$\mathrm{bdtrc}(k, n, p) = I_{p}(k + 1, n - k).$

Wrapper for the Cephes [1] routine bdtrc.
