Compared with the other five common grey models that do not consider the lead-lag influence of the system, GAPM has better predictive ability. Therefore, the introduction of the new model constructed by using the lead-lag factor is reasonable and effective in the case of community group buying...
The existing model can't cover all those problems above and the lacking of a unified form both has brought inconvenience to rotor system dynamic modeling. The approach of helicopter lead-lag damper dynamic characteristic modeling based on the fractional calculus theory is attempted to cover ...
driven one. According to the lead–lag model, one sequence can become a foreground vane for another one at some stage, which is useful for investors to make valuable decisions. In terms of methodology, a variety of approaches have been adopted to explore the linkages between crude oil market...
paper认为需要找这样的leading sort variables,既能够捕捉到这种lead-lag effects,又能够表征这种不同coverage的差异。前者analysts coverage导致lead-lag effect减弱时generally,但是后者只会对industrial factor有影响(如果假设这样的former & latter调整模型:Model:Earnings = Industry factor+ Location Factor+ Firm-specific...
The goal of the present paper is to develop an analytical helicopter body-flap-lag mathematical model and obtain insight into the response of the poorly damped lead-lag mode to cyclic control input excitations. It is known that such controls may result in pilotinduced body roll and pitch ...
In this paper, we applied the topic modeling algorithm (the LDA model) and the time series analysis to conduct the lead-lag analysis and identify different topic evolution patterns for preprints from arXiv and papers from Web of Science (WOS) in astrophysics during the last twenty years (1992...
In this paper we examine the lead–lag interaction between the futures and spot markets of the S&P500 using the threshold regression model on intraday data. The use of threshold variables to model the changes in the regression structure with respect to different market conditions enables us to ...
and decay ratios were calculated by 121 code runs with different lead-lag time constants, discovering the effect of lead-lag controller on dynamic response... Tsai,CW,Shih,... - 《Enrgy Proced》 被引量: 1发表: 2012年 Development of a tablet press feed frame lead lag determination model us...
An approximate second order model of a sun seeker control system is controlled using lead, lag, and lead-lag controller. The response of these controllers is compared with the proposed robust controller. Subsequently it is observed that the robust controller outperforms in providing reliability and ...
Our framework is validated on both a synthetic generative model for multivariate lead lag time series systems and daily real world US equity prices data. We showcase that our method is able to detect statistically significant lead lag clusters in the US equity market. We study the nature of ...
