<p class="MsoNormal">Is it possible to estimate the dispersion parameter of the negative binomial GLM using maximum likelihood in ADMB (i.e. admbglmm) and if so why is this possible given others use two component iterative methods such as the EM algorithm or
profiling over the dispersion parameter? <o:p></o:p></p>
