| Outline of Final Research Achievements |
In various academic fields, it is often required to handle measurements which can be expressed as angles. Examples of such measurements include wind directions in meteorology and torsional angles in molecular biology. In practice, it is common that angular measurements are recorded with other linear and/or circular measurements. In our study, we have studied statistical methods for multivariate data which include angular observations. Specifically, we have proposed the following three models, among others, and obtained their statistical properties: families of distributions on the general-dimensional torus, a random effect model for circular data, and a Bayesian network model for linear-circular data.
