Autoregressive moving average (ARMA) models were used to describe the autocorrelation structure over time. Three time series were analyzed for each tree: the stable carbon isotope ratio (delta(13)C); discrimination (delta); and the difference between ambient and internal CO(2) concentrations (c(...

协变量的时间序列模型(Covariate Time Series Models)通常用于描述多个时间序列之间的关系,其中一个或多个外部因素(协变量)可能对目标变量的变化产生影响。这种模型通常用于预测和建模,其中协变量可能是时间序列数据之外的外部因素,如天气、节假日、社会经济指标等。 常见的协变量时间序列模型包括: 1. 该模型用于分析...

时间序列(time series)数据是一种重要的结构化数据形式,时间序列数据主要有以下几种: 时间戳(timestamp),特定的时刻。 固定时期(period),如2007年1月或2010年全年。 时间间隔(interval),由起始和结束时间戳表示。时期(period)可以被看做间隔(interval)的特例。 实验或过程时间,每个时间点都是相对于特定起始时间的...
PlotJuggler makes it easy to visualize data but also to analyze it. You can manipulate your time series using a simple and extendable Transform Editor. Alternatively, you may use the Custom Function Editor, that allows you to create Multi-input / Single-output functions using a scripting language...
