Sims criticized the way the latter models were specified, and questioned in particular the exogeneity assumptions common in simultaneous equations modelling. These models were advocated by Sims (1980) and used since then by many economists and econometricians as alternatives to classical simultaneous equations models. In macroeconomic analysis the term ‘variance decomposition’ or, more precisely, ‘forecast error variance decomposition’ is used more narrowly for a specific tool for interpreting the relations between variables described by vector autoregressive (VAR) models.

How to get forecast variance decomposition from eviews 10 series#

VAR in EViews As an example of VAR estimation in EViews, consider two time series of returns of monthly IBM stocks and the market portfolio returns from Fama-French database (data is contained in IBM1.wf1). comp(10,t) gdp cpi gdp m1 performs the same variance decomposition as above using a different ordering. The forecast variance decomposition determines the proportion of the variation Yjt due to the shock Ujt versus shocks of other variables uit for i j. Factor analytic methods have, for instance, been used extensively in economic forecasting (see for example, Forni et al. The second line tabulates the variance decompositions of GDP up to 10 periods using the ordering as specified in VAR1. the exact same steps as previously to produce a forecast from this equation. For example, factor analysis or principal components are tools that are in widespread use. As I noted earlier, variance decomposition gives the forecast error variance for each variable that is attributable to its own shocks and shocks in the other variables in the system. Another traditional application of wavelets is to variance decomposition. You can order EViews by calling (949) 856-3368 or writing to.

How to get forecast variance decomposition from eviews 10 manuals#

The manuals can be accessed within the program through the Help function.

I would suggest trying a suite of methods and see what works best results in models with the most accurate forecasts.

EViews 10 no longer comes with a hard copy of the four manuals, a User’s Guide (2 books), a Command Reference, and an Object Reference book. Decomposition is good for time series analysis, but generally unusable for time series forecasting. Variance decomposition is a classical statistical method in multivariate analysis for uncovering simplifying structures in a large set of variables (for example, Anderson, 2003). various product information at the firm’s Web site. Decomposition is a statistical task in which the Time Series data is decomposed into several component or extracting seasonality, trend from a series data. Meaning i have taken the variance decomposition of each variable after passing 10 years.
