Assignment of \({F}({t})\times \text{ }{intervention}\) and \({F}({t})\times \text{post-time}\) during the lag period for different lag lengths \({L}\). Panels a and b depict the assignment results of variables \(F\left(t\right)\times \text{ }{intervention}\) and \(F\left(t\right)\times \text{post-time}\) (for the CSR model, they depict the assignment results of variables \({intervention}\), and \(\text{post-time}\)) for different lag lengths \(L\) (2, 4, 6, 8, 10) during the lag period for the three different models (CSR, OSR-RuLU and OSR-Sig), respectively. Different colors represent different lag lengths \(L\). Blue indicates \(L\)=2, orange indicates \(L\)=4, red indicates \(L\)=6, cyan indicates \(L\)=8, and green indicates \(L\)=10
