ggbgetRMS

agesi

<code>data.frame</code> with columns, <code>$pop1</code>, <code>$pop2</code>, <code>$deaths</code>, <code>$date1</code>, <code>$date2</code>, and <code>$age</code>.

codi

Called by <code>ggbgetAgesFit()</code> whenever the user does not want to manually determine the age range used to determine registration coverage. Probably no need to be called by top-level users. If a user would rather determine the optimal age range some other way, then look to <code>ggbcoverageFromYear()</code> where <code>ggbgetRMS</code> is called and add another condition or make it call something else.

A set of three two-census methods to the estimate the degree of death registration coverage for a population. Implemented methods include the Generalized Growth Balance method (GGB), the Synthetic Extinct Generation method (SEG), and a hybrid of the two, GGB-SEG. Each method offers automatic estimation, but users may also specify exact parameters or use a graphical interface to guess parameters in the traditional way if desired.
