It is argued that for some series, observations that are ordinarily thought of as equidistant in time are actually irregularly spaced in a more natural time scale. Section A discusses point or impulse sampling of related series and 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. ER -
