It is common in regression discontinuity analysis to control for third- or fifth-degree polynomials of the assignment variable. Such models can overfit. leading to causal inferences that are substantively implausible and that arbitrarily attribute variation to the high-degree polynomial or the discontinuity. This paper examines two recent studies that make use of regression discontinu... https://www.diegojavierfares.com/mega-save-8-tall-Faux-Crystal-Beaded-Candle-Holder-Centerpiece-great-buy/
