Description
These are a series of Matlab routines to carry out a hierarchical linear model of fish population trajectories that includes a linear adjustment for a "reserve effect" at sites designated as MPAs.
%The model is set up as follows:
%FIRST LEVEL-------------------------------------------------------------------------------------------------------
%MODEL:***** y~ intercept + abundance_index * (S_g + R_t +R_nt) + error ***
%where:
%S_g is the slope for a given species in a given geographic region (drawn
%from a normally distributed species specific hyperparameter)
%R_t is a species specific additive adjustment to the slope that is drawn
%from a normally distributed hyper parameter representing the reserve effect on harvested species. Activated by a dummy variable.
%R_nt is the species specific additive adjustment to the slope that is drawn from a normally distributed hyper parameter
%representing the reserve effect on non-harvested species. Activated by a dummy variable.
%both intercept and error terms are nuisance parameters and do not need hyperparameters. I suppose you could put in an
%error hyper parameter with an informative prior just to keep the model in check.
%SECOND LEVEL (hyper parameters all normally distributed)-----------------------------------------------------------
%S_g_hat -- These are slopes for a given species from which S_g's are drawn
%R_t_hat -- This is the reserve effect for targeted species from which R_t's across targeted species are drawn
%R_nt_hat -- This is the reserve effect for non-targed species from which
%R_nt's across non-targeted species are drawn
