This function calculates the Rao-Stirling diversity index of a single publication, based on the count of citations to different disciplines.
Note that this function returns the correct result if a vector of proportions is supplied as input. Since a normalization by (approximately) 1.0 is performed, the result is identical to the result of the function RaoProportions
up to numerical precision.
1 | RaoCounts(counts, similarity)
|
counts |
A vector of counts of citations to different disciplines of a single publication. The length of the vector should be equal to the total number of disciplines. |
similarity |
A positive semi-definite matrix that encodes the similarity between disciplines, as explained in Porter and Rafols (2009).
The dimensions of this matrix are n x n, being n the total number of disciplines.
The number of rows and the number columns of this matrix need to be equal to the length of |
The Rao-Stirling diversity index of a publication.
