We can use time-series modeling techniques to model the data at the discontinuity. Time series discontinuities are some of the most believable RD designs in practice, so we’ll cover this special case here. greater manchester volleyball league

Webb2 juli 2016 · It has been recognized that the two-phase version of the interrupted time-series design can be frequently modeled using a four-parameter design matrix. There are differences across writers, however, in the details of the recommended design matrices to be used in the estimation of the four parameters of the model. Webbstudies that utilize basic interrupted time-series designs, the validity of these inferences can be questioned because a shift in the time series may be the result of something other than the treatment (e.g., an event that happened to occur around the time of the intervention; Shadish, Cook, & Campbell, 2002).
