Conventional DM vs. Quasi-FMDM 3.85***
Conventional DM vs. FMDM 3 98***
Quasi-FMDM vs. FMDM 0.15

indicates significance at the 1% level. Under the null hypothesis of equivalence between Models A and B, the Rivers-Vuong test statistic is standard normally distributed. A positive (negative) statistically significant test statistic suggests that Model B (A) is preferred to Model A (B).
