Take the difference, use the fact that E(Yi(0)|Xi = x) is c<strong>on</strong>tinuous<br />

at Xi = c and solve for τFRD.<br />

limx↓cE(Yi|Xi = x) − limx↑cE(Yi|Xi = x)=<br />

limx↓cE(Wi|Xi = x) − limx↑cE(Wi|Xi = x)τFRD<br />

τFRD = lim x↓cE(Yi|Xi = x) − limx↑cE(Yi|Xi = x)<br />

limx↓cE(Wi|Xi = x) − limx↑cE(Wi|Xi = x)
