scipy.special.bdtri#
- scipy.special.bdtri(k, n, y, out=None) = <ufunc 'bdtri'>#
- Inverse function to - bdtrwith respect to p.- Finds the event probability p such that the sum of the terms 0 through k of the binomial probability density is equal to the given cumulative probability y. - Parameters:
- karray_like
- Number of successes (float), rounded down to the nearest integer. 
- narray_like
- Number of events (float) 
- yarray_like
- Cumulative probability (probability of k or fewer successes in n events). 
- outndarray, optional
- Optional output array for the function values 
 
- Returns:
- pscalar or ndarray
- The event probability such that bdtr(lfloor k rfloor, n, p) = y. 
 
 - See also - Notes - The computation is carried out using the inverse beta integral function and the relation,: - 1 - p = betaincinv(n - k, k + 1, y). - Wrapper for the Cephes [1] routine - bdtri.- References [1]- Cephes Mathematical Functions Library, http://www.netlib.org/cephes/
