Taking account of sample size in the GLM analyses of the response variable data from the island closure feasibility study

Author: Butterworth, Doug S ; Ross-Gillespie, A Date: 2014 Two approaches are used to examine the impact of taking sample size into account in GLM analyses to estimate the fishing effect parameter λ. In the first the variance of each mean value input to the analyses is disaggregated into separate ... Read more
Taking account of the new longline data in the updated Reference Case for the South African hake resource

Testing an alternative CMP approach where the 2019 and 2020 TACs are fixed at 10% above the 2018 value

Author: Ross-Gillespie, Andrea ; Butterworth, Doug S Date: Oct 2018 Results for an Alternative CMP where the 2019 and 2020 TACs are fixed at the 2018 value plus 10% are compared to the Base CMPs. Simulations based on the Reference Set OMs suggest that the Alternative CMPs are likely to result in higher ... Read more
Testing for a common latent variable in a linear regression: Or how to "fix" a bad variable by adding multiple proxies for it
