In this paper we extend Rydberg-Shephards acivity, direction and size decomposition of trade-by-trade price movements …

are easily extended in a great number of directions, including using durations and volume as explanatory variables. Thus …In this article we introduce a decomposition of the joint distribution of price changes of assets recorded trade …-by-trade. Our decomposition means that we can model the dynamics of price changes using quite simple and interpretable models which …

While many of the insights drawn from this perspective have merit and suggest elements … governing likely future directions for HPC, there are a number of points put forth that we feel require further discussion and … high performance computing environments. This paper addresses the key issues of taxonomy, future directions towards …

Human capital is a vital component in the production process, so the size of the labor force can profoundly affect the … participation behavior and population shares. The decomposition reveals that a decline in the population shares of working-age men … estimates from more complex structural forecasting models. …

An interesting approach to economic and financial time series forecasting consists of decomposing an input time series … series. The present paper considers one very important aspect of the forecasting procedure. More specifically, it provides a … better understanding of how an additive decomposition of the input time series into several components can be obtained using …
