Restricted active space (RAS) configuration interaction (CI) approach is employed to compute the $P$, $T$ -odd interaction constant $W_{d}$ for the ground ($^{2} \sum_{1/2}$ ) state of YbF molecule. The present estimate of $W_{d} = −1.164 \times 10^{25}$ Hz/e-cm is expected to provide a reliable limit on the electron's electric dipole moment (EDM), $d_{e}$.
