Before revision:  The linear contraction parameter captures the relative attitudes of the DM towards ML with respect to FB . In particular, when the parameter takes either one of the two extreme values (0 or 1), RML reduces to FB or ML respectively. This paper also characterizes the Extended RML updating rule for ex-ante preferences that in addition satisfy comonotonic independence. This rule, which is related to RML, further preserves comonotonic independence for the updated preferences
After revision:  The linear contraction parameter captures the relative attitudes of the DM towards ML with respect to FB , it is also the threshold of a relative likelihood ratio test. Moreover, RML includes both FB and ML as the two extreme special cases. Additionally, the present paper provides an axiomatization of ML for preferences admit Maxmin Expected Utility (MEU) representation as a preliminary result for the exposition of RML.
