The output is a table with one row per model comparison as follows:

<table border="1"><tr><td>base</td><td>comparison</td><td>ep</td><td>minus2LL</td><td>df</td><td>AIC</td><td>diffLL</td><td>diffdf</td><td>p</td></tr>

Name of the base model Name of the comparison model Estimated parameters of the comparison model Minus 2log-likelihood of the comparison model Degrees in freedom of the comparison model Akaike's Information Criterion for the comparison model Change in minus 2log-likelihood Change in degrees of freedom Significance level of the change in fitness function
