#TEST FOR COINTEGRATION XLSTAT SERIES#
It is not limited to two time series and allows you to test the existence of multiple cointegrating relationships. This approach, implemented in XLSTAT, is based on Vector Autoregressive (VAR) models. One of the most interesting approaches for testing for cointegration within a group of time series is the maximum likelihood methodology proposed by Johansen (1988, 1991). Those stationary combinations are called cointegrating equations. In other words, there exists one or more linear combination of those I(1) time series (or integrated of order 1, see unit root test) that is stationary (or I(0)). It identifies a situation where two or more non stationary time series are bound together in such a way that they cannot deviate from some equilibrium in the long term. The term of cointegration was first introduced by Engle and Granger (1987) after the work of Granger and Newbold (1974) on spurious regression. In finance, such relationships are expected for instance between the prices of the same asset on different market places. Examples of such relationships in economics include money with income, prices and interest rates or exchange rate with foreign and domestic prices. We say that those variables are cointegrated. Although those variables can derive from each other on a short term basis, the economic forces at work should restore the original equilibrium between them on the long run. What are cointegration tests?Įconomic theory often suggests long-term relationship between two or more economic variables. Political Analysis, 9(1):78–94.Use this module to perform VAR-based cointegration tests on a group of two or more I(1) time series using the approach proposed by Johansen (1991, 1995). Modeling equilibrium relationships: Error correction models with strongly autoregressive data. Co-integration, error correction, and the econometric analysis of non-stationary data. On the other hand: you don't have tons of data, so I suppose it depends how many new variables you are adding.īanerjee, A., Dolado, J. some policies go into effect January 1, some July 1, some December 21, etc.). I have done something similar, but used (time-varying) proportions (rather than 0/1 indicator variables) to represent the portion of the time period during which a policy was in effect (e.g. The time dummies can be included in the GECM model, and presumably other dynamic times series models, often they are used as indicators of, for example, policies going into effect. I do not know that I can say much useful here. In Stata you can perform Hadri's test for unit-root in panel data on the residuals of such a model, to check them for stationarity. I haven't yet tried to derive a heterogeneous error correction specification. This specification assumes a homogeneity of error correction processes. Its a secondary data taken from OECD website mostly. Nerus at Bukit, Terengganu), out of 156 observations only 7 residuals were outside the -1.96, 1.96 range, an analysis that does not lead us to reject the normality. As in the scatter plots represented in the figure 2 for Station 4 (Site: 5229436 SG.
#TEST FOR COINTEGRATION XLSTAT SOFTWARE#
I am running a panel fixed effects regression on 21 countries and 16 years. This software XLSTATs data flagger brought those values which are not in the interval out.
