CatDynCor: Correlation Plot Among Parameter Estimates

In CatDyn: Fishery Stock Assessment by Catch Dynamics Models

Description

It extracts the correlation matrices output by CatDynFit() from several model fits and plots histograms of pairwise correlation coefficients.

Usage

CatDynCor(x, ttl, method, arr)

Arguments

x	A list of model objects of class catdyn output by CatDynFit().
ttl	A character vector to use as title of each histogram.
method	A character vector of numerical methods to extract correlation matrices.
arr	A numerical vector of length 2 used to organize the panels containing each histogram. Passed as is to par().

Details

The arguments x, ttl, and method must be of the same length.

It might be useful to examine the results of different numerical methods applied to the same model with this function. To do this just repeat the name of the object in x and specify the different numerical methods in method.

Value

A multiple panel correlation plot.

Note

Those histograms that show more correlations concentrated around zero indicate a better fit.
