paleoTS (version 0.4-1)

compareModels: Compare output from any set of model fits

Description

Function compares a series of objects of paleoTSfit output from any of the model-fitting functions.

Usage

compareModels(..., silent = FALSE)

Arguments

...

a series of one or more paleoTSfit objects, separated by commas

silent

if TRUE, results of model comparison will not be printed to the screen

Value

• If silent=FALSE, returns a dataframe with the above information. If silent=TRUE, returns a list of the dataframe summarizing model fits along with the maximum-likelihood estimates for the parameters in each model.

Details

This function offers a convenient way to view the performance of multiple fitted models. Log-likeihoods, numbers of parameters (K), AICc scores and Akaike weights are returned in a table. The function checks that all model fits use the same method (parameterization; AD or Joint). If they do not, an error message results. Model fits are only comparable if they are based on the same parameterization.
