The staple of econometrics textbooks, the simultaneous equations model, is a multivariate model; and when the data are time series it becomes a multivariate time series model. John Geweke (1978) laid out the connection of the notation and standard assumptions of simultaneous equations modelling to ...

摘要:华为云数据库创新Lab在论文《MARINA: An MLP-Attention Model for Multivariate Time-Series Analysis》中提出了华为自研的自回归时序神经网络模型,可用于时序数据的预测以及异常检测。 本文分享自华为云社区《CIKM'22 MARINA论文解读》,作者: 云数据库创新Lab 。 华为云数据库创新Lab在论文《MARINA...
一是不同传感器之间有着非常不同的行为,即图中节点的数值和分布差异很大,因此需要考虑如何对传感器,即图中节点进行特征表示;二是GNNs的输入必须是整个图,即包括图中节点的特征表示以及各节点的连接关系,而在本文场景中,各节点之间的关系都是未知的(以往的方法是直接认为各节点之间都存在关系,即使用完全图表征各节点...

One approach is to fit a suitable ARIMA or other linear time series model and then apply the usual Ljung-Box portmanteau test to the squares of the residuals. McLeod and Li (1983) suggested this as a general test for nonlinearity. The built-in function Box.test() provides a convenient fun...
The simulation results based on the real data collected from the Rufiji Delta, Tanzania, show that this kind of model is well suited to predicting suspended sediment concentration and transportation of sediment. 展开 关键词: multivariate time-series model suspended sediment concentration current velocity...
