Calculate Euclidean index for an author.

An Euclidean index of a vector is the square root of the sum of the squared elements.

Parameters:	arr (array-like) – Array of citations. ignore_nan (bool (optional, default=True)) – If True, remove nan values and return 0 if all values are nan.
Returns:	eui – Euclidean index of the author for the given citations.
Return type:	float

Examples

>>> from scholarmetrics import euclidean
>>> citations = [6, 10, 5, 46, 0, 2]
>>> euclidean(citations)
47.75981574503821

Notes

The Euclidean index was originally proposed by Motty Perry and Philip J. Reny [eu].
