cupy.nanstd¶

cupy.nanstd(a, axis=None, dtype=None, out=None, ddof=0, keepdims=False)[source]¶

Returns the standard deviation along an axis ignoring NaN values.

Parameters:	a (cupy.ndarray) – Array to compute standard deviation. axis (int) – Along which axis to compute standard deviation. The flattened array is used by default. dtype – Data type specifier. out (cupy.ndarray) – Output array. keepdims (bool) – If `True`, the axis is remained as an axis of size one.
Returns:	The standard deviation of the input array along the axis.
Return type:	cupy.ndarray
