</blockquote><h2>Description</h2><blockquote>
<p>The file ConnDiefenbach_ModelSelection.SAS includes
requisite code to compute log likelihoods for different aging error models evaluated
at their MLEs (maximum likelihood estimates). These are useful for calculating model
selection criterion. The file ConnDiefenbach_AgeError_1year.SAS includes code for estimating the standing age distribution of female black bear
harvests in
Pennsylvania. Because of the potential for algorithm
instability when these distributions are estimated simultaneously across all
years, this code permits estimation of age distributions 1 year at a time (which
year must be specified by the user).</p>
