A mistake was discovered in the calculation of the Log Likelihood sum of the CoupModel.
The two possible methods availabe based on the Gaussian distribution or a non Gaussian distribution according to Sivias
include both a constant value
This constant has not been defined in version of the CoupModel prior March 3th. This mean that the LogLikelihood values that
are reported are to high = n*the constant. The good news is that this does not have any direct impact on the calibration. However
for comparision with other calculation we have to include this constant number.
