  In this paper, we classify three-dimensional Lorentzian Lie groups on which
Ricci tensors associated to Bott connections, canonical connections and
Kobayashi-Nomizu connections are Codazzi tensors associated to these
connections. We also classify three-dimensional Lorentzian Lie group with the
quasi-statistical structure associated to Bott connections, canonical
connections and Kobayashi-Nomizu connections.
