Package: PiChange Title: Pi-Change: Change Point Detection with Prior-Informed Penalties Version: 0.0.6 Authors@R: c( person("Jonathon", "Jacobs", role = c("aut", "cph"), email = "jacobsjr@vcu.edu"), person("Shanshan", "Chen", role = c("aut", "cre", "cph"), email = "schen3@vcu.edu") ) Description: PI-Change is a prior-informed multiple change point detection method that incorporates prespecified plausible change point locations through a time-varying penalized likelihood. The method extends multiple change point detection beyond purely data-driven segmentation by allowing external knowledge about plausible change point locations to enter the objective function; see Jacobs and Chen (2026) .
