Circular Data Analysis of Periodic Time Series Data Using Grey Theory
Circular data can be expressed as circular diagram for time series data. This study presents the computational procedure, which made circular diagram for the data with periodicity. The method for displaying circular diagram using spline function and GM(1,1) model of the Grey Theory is developed to analyze the periodic data. In addition, the method for displaying the fluctuation of the periodic data from least squares method, GM(1,1) model and periodic spline function is shown.
