In other words Why can't we simply use, say, the R-squared between X or Y to see if X and Y have some kind of relationship? A Handbook of Statistical Analyses Using R http://www.pinggu.org/bbs/thread-361805-1-1.html. R is the number of co-integrating relations (the cointegrating rank) and each column of β is the cointegrating vector. Analysis of Integrated and Co-integrated Time Series with R (Use R) http://www.pinggu.org/bbs/thread-356363-1-1.html. Suppose that ut is an observable time series, not adjusted for seasonality, i.e. In more technical terms, if we have two non-stationary time series X and Y that become stationary when differenced (these are called integrated of order one series, or I(1) series; random walks are one example) such that some linear combination of X and Y is stationary (aka, I(0)), then we say that X and Y are cointegrated. Usually exhibit large seasonal fluctuations. In the summary below, I will briefly convey a statistical The whole idea of Johansen test is to decompose PI into two n by r matrices, α and β, such that PI = α * β` and β` * Y_t is stationary. As in the stat workshop supporting the loss forecasting, my analysts and I are frequently asked to quantify the “correlation” between time series. The traditional approach to this issue has been to consider the seasonality in these series as non-informative (in an economic sense) and therefore use seasonally adjusted data for their analyses.
