Gammainc in python
Web1 Answer Sorted by: 47 By default, "import scipy" does not import any subpackage. There are too many subpackages with large Fortran extension modules that are slow to load. I do not recommend doing import scipy or the abbreviated import scipy as sp. It's just not very useful. Use from scipy import special, from scipy import linalg, etc. Share WebInverse of Incomplete Gamma Function. The inverse of the lower incomplete gamma function is defined as x = P − 1 ( y, a), such that. y = P ( x, a) = 1 Γ ( a) ∫ 0 x t a − 1 e − t d t. The inverse of the upper incomplete gamma …
