hpd-index

The hpd-index (Kosmulski 2009) is very similar to the h-index, except that it adjusts for the age of a publication. Rather than adjust per year, the metric is adjusted per decade. Thus if

$$cpd_i=\frac{10C_i}{Y-Y_i+1}$$

is the number of citations an article has per decade (where Y is the current year), then the hpd-index for an author is the largest rank for which hpd of their publications (ranked by cpdi rather than Ci) have cpdhpd.

$$hpd=\underset{i}{\max}\left(i \leq cpd_i\right)$$

Example

Publications are ordered by adjusted number of citations, from highest to lowest.

Citations (Ci)36421411299212311000

The largest rank where icpdi is 9.
