Dear list

I have a data set involving binary responses (successes failures) for which
some explanatory variables result in a quasi complete separation problem.
To deal with the separation problem I tried to run a glm with "bayesglm" in
the arm package. 

However when I try to compare different bayesglm models, the anova doesn't
give any value. 

> anova(model1,model2,test="Chi")
Analysis of Deviance Table
  Resid. Df Resid. Dev Df   Deviance Pr(>Chi)
1       336     118.67                       
2       336     118.68  0 -0.0069818         

Does anyone know how to solve this problem ?
Thank you in advance for your time and for any advice you could provide

Best regard
