Repository for evaluation of VAST package for single and multispecies spatial delta-generalized linear mixed models (delta-GLMM). The purpose of this analysis is to evaluate differences in indices and uncertainty estimates generated by VAST and design-based estimators, for a range of species in the Bering Sea and Gulf of Alaska.
Probably need to figure out how to do design-based estimates for the EBS and or Aleutian Islands too. Right now you only have GOA stocks (we probably wanted BSAI Atka mackeral, not GOA for example). I am interested in comparing how the VAST model behaves with structured grid data like EBS versus random data like GOA.
Currently limited to GOA because of repeating strata numbering system. Relatively easy fix with better lookup in design-based function and probably adding region as column to input .xlsx file with species.
