In some applications of the distributed lag model, theory requires that all lag coefficients have a positive sign. A … distributed lag estimator which provides estimated coefficients with positive sign is developed here which is analogous to an … earlier distributed lag estimator derived from "smoothness priors" which did not assure that all estimated coefficients be …

suggested by Hoerl and Kennard. It is shown that for the estimation of distributed lag models the ridge estimator suggested by …

the estimation of distributed lag relationships between them. Section B discusses time-aggregated sampling. In Section C …, operational-time methods are used to calculate the distributed lag relationship between starts and completions for single …-family dwellings in the United States. The results are statistically compared with those of ordinary distributed lag methods …
