Utilising data from ecosystem monitoring for managing fisheries: development of statistical summaries of indices arising from the CCAMLR Ecosystem Monitoring Program
Program, two lengths of time were investigated: 10 and 20 years. The correlation matrix was estimated ... total length of the time series (20 years was better than 10) and the proportion of the time series in ... increase from 10- to 20-year time series resulted in little change in the median performance but in a ... replicates. Smoothing occurred in less than 50% of replicates in some of the 20-year time series for which ...
