NFix

Normal prior where, in contrast to <code>N()</code>, the
variance is treated as fixed and known. Typically
used for main effects or interactions where there
are too few elements to reliably estimate variance
from the available data.

Fast Bayesian estimation and forecasting of age-specific
rates, probabilities, and means, based on 'Template Model Builder'.
