1. Evaluation of de la Mare’s composite standardised index for generating a simple time-series summary of many long-term datasets on Antarctic predators: consequences of missing values and criteria for inclusion of predator parameters

   Abstract:  In 1997, de la Mare presented a statistic (labelled the Composite Standardised Index at ... the Workshop on Area 48) to WG-EMM for generating a simple time-series index of many long-term ... datasets on Antarctic predators. The value of the index in a given year is dependent on the specific ... correlated the parameters are to each other. This paper reports on a Monte Carlo simulation study that helps ...
