scipy.special.pdtrc#
- scipy.special.pdtrc(k, m, out=None) = <ufunc 'pdtrc'>#
Poisson survival function
Returns the sum of the terms from k+1 to infinity of the Poisson distribution: sum(exp(-m) * m**j / j!, j=k+1..inf) = gammainc( k+1, m). Arguments must both be non-negative doubles.
- Parameters:
- karray_like
Number of occurrences (nonnegative, real)
- marray_like
Shape parameter (nonnegative, real)
- outndarray, optional
Optional output array for the function results
- Returns:
- scalar or ndarray
Values of the Poisson survival function
