How to do Vecm in Excel
Vector Error Correction Model (VECM) is a type of time series model used when dealing with cointegrated series. It’s essentially a multivariate generalization of the Error Correction Model (ECM), which allows you to model both short-term dynamics and long-term relationships among several non-stationary time series variables. VECM is a staple in econometrics, particularly useful when you are dealing with non-stationary data that are cointegrated.
Implementing a VECM in Excel is quite complex and not straightforward because it involves several advanced statistical computations, which include Johansen’s cointegration test, estimation of cointegration vectors, and building the actual error correction terms. Typically, statistical software such as R, EViews, or Stata is used for such advanced econometric modeling because they have built-in functions to handle these complex calculations efficiently.
