scipy.special.chndtrix#
- scipy.special.chndtrix(p, df, nc, out=None) = <ufunc 'chndtrix'>#
Inverse to
chndtr
vs xCalculated using a search to find a value for x that produces the desired value of p.
- Parameters:
- parray_like
Probability; must satisfy
0 <= p < 1
- dfarray_like
Degrees of freedom; must satisfy
df > 0
- ncarray_like
Non-centrality parameter; must satisfy
nc >= 0
- outndarray, optional
Optional output array for the function results
- Returns:
- xscalar or ndarray
Value so that the probability a non-central Chi square random variable with df degrees of freedom and non-centrality, nc, is greater than x equals p.
