Karhunen-Loève Analysis of Historical Time Series with an Application to Plantation Births in Jamaica
历史时间序列的Karhunen–Loève分析:牙买加种植园出生数据应用
A comparison of two spectral analysis procedures is presented: the frequency domain (Fourier transform) model and the Karhunen-Loève time domain model. Both models are used in turn to analyze a plantation births series during the period 1880–1938. The principal components model can be adapted as the discrete analogue of the Karhunen-Loève stochastic integral equation in order to decompose a single time series into trend, cycle, and seasonality. The results indicate that the…
