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:
| base | comparison | ep | minus2LL | df | AIC | diffLL | diffdf | Significance |
|---|---|---|---|---|---|---|---|---|
| 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 2*log-likelihood | Change in degrees of freedom | Significance level of the change in fitness function |
