scipy.special.pdtrik#
- scipy.special.pdtrik(p, m, out=None) = <ufunc 'pdtrik'>#
Inverse to
pdtr
vs k.- Parameters:
- parray_like
Probability
- marray_like
Shape parameter (nonnegative, real)
- outndarray, optional
Optional output array for the function results
- Returns:
- scalar or ndarray
The number of occurrences k such that
pdtr(k, m) = p

Examples
>>> import scipy.special as sc
Compute the CDF for several values of k:
>>> k = [1, 2, 3] >>> p = sc.pdtr(k, 2) >>> p array([0.40600585, 0.67667642, 0.85712346])
Compute the inverse. We recover the values of k, as expected:
>>> sc.pdtrik(p, 2) array([1., 2., 3.])
