The source code for Stock Synthesis (SS3).
### Describe the solution you would like. I think the current implementation of the depletion survey option assumes the first year entered is at unfished. It would be great to...
Imported from redmine, Issue [#56287](https://vlab.ncep.noaa.gov/redmine/issues/56287) Opened by @RickMethot on 2018-10-15 Status when imported: On Hold The following code seems incomplete in its logic. Currently, if R0 is time-varying, SS will...
I'm leading a paper with Tim Miller and Brian Stock, introducing a new "multivariate-Tweedie" likelihood for fitting age/length composition data. It is essentially a more flexible alternative to the Dirichlet-multinomial,...

### Describe the solution you would like. In many cases I believe it is more statistically justifiable to use a more flexible index likelihood than the lognormal. One appealing alternative...
### Describe the solution you would like. per a conversation with Arni Magnusson, dynamic Bzero may function differently if recdev option 3 or 4 is selected because with those options...
### Describe the solution you would like. As discussed during ongoing ICES course on SS3, expanding the M option 3 to allow a matrix of M by age and year...
