statistical =========== Satistical functions expected by the python array API Internally, all functions apply a reduction operation on a LinearSpaceElement. Args: x (LinearSpaceElement): LinearSpaceElement on which to apply the reduction. Returns: x (float | array-like): Output of the reduction. Notes: 1) The actual implementation of the reduction is in the LinearSpace of this element. 2) These functions can return python Numbers or backend-specific array (when calling with keepdims=True for instance), but they will not return odl objects. .. currentmodule:: odl.core.array_API_support.statistical
