Hello Ayman,
If I understand, you have a 0,1 variable as your outcome and a continuous running variable. You can do this with standard OLS and it is the classic RD setup. Perhaps your concern is the polynomial choice in the running variable (independent)?

However, the package assumes that the dependent variable is continuous and uses a polynomial to fit a local regression.
