Cointegration is an important tool for modeling the long-run relationships in time series data. If you work with time series data, you will likely find yourself needing to use cointegration at some point.This blog provides an in-depth introduction to cointegration and will cover all the nuts ...
Intuition: Linear combination of time series (which form cointegrating relationship) is determined by underlying (long-term) economic forces, e.g., same industry companies may grow similarly; spot and forward price of financial product are bound together by no-arbitrage principle; FX rates of inter...
used to determine time series short-run deviations from long-run equilibrium. The simple SAS techniques covered in all 3 parts of this series can be used with the more complex SAS routines such as PROC ARIMA, which require high level of research and analysis expertise (Bails & ...
This paper examines several US monthly financial time series using fractional integration and cointegration techniques. The univariate analysis based on fractional integration aims to determine whether the series are I(1) (in which case markets might be efficient) or alternatively I(d) with d<1, wh...

A cointegration test is used to establish if there is a correlation between several time series in the long term. The concept was first introduced by Nobel
如果用平稳的分析刻画一个均值/方差随时间变化的时间序列,那么将会导致garbage in garbage out。 例如,下图series B,是一个随着时间t而均值不断增大的曲线。 测试平稳性:使用augmented Dickey Fuller test,P值越小,说明越可能是平稳的时间序列。 from statsmodels.tsa.stattools import adfuller ...
Usual full-order VECMs assume all nonzero entries in their coefficient matrices. However applications of VECMs to economic and financial time series data have revealed that zero entries are indeed possible. If indirect causality or Granger non-causality exists among the variables, the use of a ...
