The steepness package computes steepness as a
property of dominance hierarchies. Steepness is defined as the
absolute slope of the straight line fitted to the normalized
David's scores. The normalized David's scores can be obtained
on the basis of dyadic dominance indices corrected for chance
or by means of proportions of wins. Given an observed
sociomatrix, it computes hierarchy's steepness and estimates
statistical significance by means of a randomization test.
