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.hindigyanvishv.com/hot-find-Facia-Installation-Kit-Suits-Holden-Commodore-VE-Series-2-FP9550BK-Black-top-mega/
