construct.vgam

Nonlinear degrees of freedom.  See VGAM documentation for more on
what this means.

constr.cols

A transformed log-linear design matrix.  The submatrix
indicated by <code>constr.cols</code> is the desired argument to the VGAM command
to impose the corresponding log-linear model on the data.

constraints

A CRC dataset in standard form (i.e., as output of
<code>format.data</code>)


A wrapper function to fit a CRC model using the vgam command in the VGAM
package.


Applies local log-linear capture-recapture models (LLLMs) for
closed populations, as described in the doctoral thesis of Zachary Kurtz.
The method is relevant when there are 3-5 capture occasions, with auxiliary
covariates available for all capture occasions.  As part of estimating the
number of missing population units, the method estimates the "rate of
missingness" as it varies over the covariate space.  In addition,
user-friendly functions are provided to recreate (approximately) the method
of Zwane and van der Heijden (2004), which applied the VGAM package
in a way that is closely related to LLLMs.
