Shiny App


Slick is a decision analysis tool that presents the outcomes of candidate harvest strategies across various states of nature, accounting for uncertainty. Slick is interactive and allows users to filter results live in order to explore robustness and performance.

While Slick can be applied to any decision analysis context it was specifically designed to investigate the performance of harvest strategies tested by management strategy evaluation (MSE). Slick can be used for any MSE process, but the current version includes a demonstration example, as well as preliminary results from the MSEs for Western Atlantic skipjack tuna and North Atlantic swordfish.
