Partially overlapping time series: a new model for volatility dynamics in commodity futures
部分重叠时间序列:商品期货波动动态的新模型
Abstract In commodity futures markets, contracts with various delivery dates trade simultaneously. Applied researchers typically discard the majority of the data and form a single time series by choosing only one price observation per day. This strategy precludes a full understanding of these markets and can induce complicated nonlinear dynamics in the data. In this paper, I introduce the partially overlapping time series (POTS) model to model jointly all traded contracts.…
