Type: Package Package: simITS Title: Analysis via Simulation of Interrupted Time Series (ITS) Data Version: 0.1.1 Authors@R: c(person(given = "Luke", family = "Miratrix", role = c("aut", "cre"), email = "lmiratrix@g.harvard.edu"), person(given = "Brit", family = "Henderson", role = "ctb", email = "Brit.Henderson@mdrc.org"), person(given = "Chloe", family = "Anderson", role = "ctb", email = "Chloe.AAnderson@mdrc.org"), person(given = "Arnold Ventures", role="fnd"), person(given = "MDRC", role="fnd") ) Description: Uses simulation to create prediction intervals for post-policy outcomes in interrupted time series (ITS) designs, following Miratrix (2020) . This package provides methods for fitting ITS models with lagged outcomes and variables to account for temporal dependencies. It then conducts inference via simulation, simulating a set of plausible counterfactual post-policy series to compare to the observed post-policy series. This package also provides methods to visualize such data, and also to incorporate seasonality models and smoothing and aggregation/summarization.
