# 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:
    k array_like

      Number of occurrences (nonnegative, real)

    m array_like

      Shape parameter (nonnegative, real)

    out ndarray, optional

      Optional output array for the function results

  Returns:
    scalar or ndarray

      Values of the Poisson survival function
