WebJul 4, 2024 · I am using the Stata rdrobust command for RDD analysis, aiming to perform a two-stage analysis. The first stage is to model the probability of receiving the treatment at cut-off and the second stage is to use the predicted value of the treatment variable on my dependent variables. WebThe RDDE is the ratio of the RDD impact variance to the RCT impact variance, holding sample size constant. Schochet (2008a) shows that in the case of an RDD analysis using a linear functional form and all available data, the RDDE reduces to: (2) RDDE 1 1 2
