| Research Abstract |
For proper assessment of living marine resources and environmental risk, it is important to develop the statistical models with the mechanisms that capture spatio-temporal patterns and characteristics in the data. We did the research on 1) defining population spatial units based on frequency distributions of animals' characteristic features and temporal trends of abundance, 2) statistical methods for zero-inflated count data such as bycatch counts, 3) statistical methods to analyze the data with doubly cyclic tempral patterns and analysis of CO2 data observed at Syowa station in Antarctica.
