Erroneous at-age CPUE data outputs under individual and mixed growth variation modes #24

Closed mckenziej closed 7 years ago

mckenziej commented 7 years ago

The catch at -age and CPUE indices produced by the IBM under individual "i" and mixed "m" growth variation settings appear to be erroneous. One manifestation of the problem is seen in the REC CPUE index which is variable compared to the other method indices. Under temporal growth variation the REC index is smooth. A run where the REC method was given the same selectivity to LL also produced a more variable CPUE trend for REC.

I believe that this is resolved with this five character bug :bug: fix: https://github.com/trophia/sna1/commit/ad02d4aa3b21d0a59b917a635d8c2318339fd717
