scholarmetrics.gindex(arr: _Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str]) → int

Calculate g-index for an author.

An g-index of x means that the author’s top x publications together accumulated at least \(x^2\) citations.

Parameters:

arr (array-like) – Array of citations.

Returns:

gi – g-index of the author for the given citations.

Return type:

int

Examples

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

Notes

The g-index was originally proposed by Leo Egghe [g]. It excludes uncited publications. nan values are silently treated as zero values.
