Frequency of index based assessments? #23

Closed rich-bell closed 4 years ago

rich-bell commented 4 years ago

Wondering if there was a decision on how frequently the index based assessments would be run, every two years, three years, etc? Joe Langan's dynamic linear model function uses a forecasting method to generate the catch advise within specifications. The function can forecast as many years of catch as needed to cover the time between assessments. Currently the default is two y$JoeDLM_n_ahead<-2 # forecasting 2 years and returning 2 years of catch advice , but was hoping this could be connected with a higher level control so the implementation of the function does not crash the simulations.

The default will be to conduct the index based assessments every other year. It would be nice to have the functions generalized to allow easy exploration of conducting assessments every year or every third year, if this isn't too much of a pain.

This is already specified in the input object input$adv.yr. Default is 2 but can be changed by the scenario specifications. This could be passed to JoeDLM() to make the forecast reactive. Seems like a low priority at the moment.
