Abstract: almon1 estimates Shirley Almon Polynomial Distributed Lag Model for many variables with the same lag order, endpoint restrictions, and polynomial degree order via (OLS - ALS - GLS - ARCH) Regression models. almon1 can compute Autocorrelation, Heteroscedasticity, and Non Normality Tests, Model Selection Diagnostic Criteria, and ... WebStandard techniques, such as those proposed by Almon and Koyck , assign weights to the lag structure in such a way that the model can be transformed into AR, ARMA, or ARMAX form. The methods are more ad hoc than data-driven, and subject to the problems of collinearity that come from working with many lags of a predictor at proximate times.
