The PDLREG procedure provides regression analysis for linear models with polynomial distributed (Almon) lags. The PDLREG procedure includes the following features:

• entry of any number of regressors as a polynomial lag distribution and the use of any number of covariates

• use of any order lag length and degree polynomial for lag distribution

• optional upper and lower endpoint restrictions

• specification of any number of linear restrictions on covariates

• option to repeat analysis over a range of degrees for the lag distribution polynomials

• support for autoregressive errors to any lag

• forecasts with confidence limits
