scipy.special.chdtri#
- scipy.special.chdtri(v, p, out=None) = <ufunc 'chdtri'>#
- Inverse to - chdtrcwith respect to x.- Returns x such that - chdtrc(v, x) == p.- Parameters:
- varray_like
- Degrees of freedom. 
- parray_like
- Probability. 
- outndarray, optional
- Optional output array for the function results. 
 
- Returns:
- xscalar or ndarray
- Value so that the probability a Chi square random variable with v degrees of freedom is greater than x equals p.
