I am pretty sure that the results of Likelihood ratio test are bigger 
than the real value. They are multiplied for the factor Ln(10), in this 
way the p-values are smaller than what they should be.
The reason is that you apply the formula -2*log(exp(L(0)/exp(L(B)) and 
not  what it should be -2*log(L(0)/L(B)).

Please if I am not right, tell me
