Usage: **mxCompare**(*base*, *comparison*, *digits* = 3)

base: An MxModel object or list of MxModel objects.

comparison: A MxModel object or list of MxModel objects.

digits: A numeric setting table decimal precision.

#### Comparing two or more models

This function is provided to allow the user to compare the fit of one or more models to a base model.

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 2

*log-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
