Abstract: Since an angular valued time series is expressed as a time series on a unit circle on the complex plane, the techniques of parameter estimation share some well-known methods in complex-valued data analysis. Recently, several fundamental properties of higher-order circular time series models have been developed, while there remain several problems in the parameter estimation for such data. This study introduces some topics among circular and/or complex-valued time series modeling.
