discounted h-index
The discounted h-index (Ferrara and Romero 2013) was designed to adjust the h-index for self-citations by multiplying it by square-root of the percentage of total citations that were not self-citations. It is readily calculated as:
$$dh=h \sqrt{\frac{C^P-S^P}{C^P}},$$where SP is the sum of self-citations for all publications.
