SSmohnsrho | R Documentation |
Function calculates:
a rho value for the ending year for each retrospective relative to the reference model as in Mohn (1999);
a “Wood's Hole Mohn's rho”, which is a rho value averaged across all years for each retrospective relative to the reference model; and
an Alaska Fisheries Science Center and Hurtado-Ferro et al. (2015) Mohn's rho, which is the average rho per retrospective “peel”.
