as.APC.df

Add 1-indexed APC columns to data frame, handling numeric or categorical age/period

Bayesian multivariate age-period-cohort (MAPC) models for analyzing health data, with support for model fitting, visualization, stratification, and model comparison. Inference focuses on identifiable cross-strata differences, as described by Riebler and Held (2010) <doi:10.1093/biostatistics/kxp037>. Methods for handling complex survey data via the 'survey' package are included, as described in Mercer et al. (2014) <doi:10.1016/j.spasta.2013.12.001>.

as.APC.df function

<dl><dt>data</dt>
<dd>Data frame with age and period columns.</dd>
<dt>age</dt>
<dd>Age column in <code>data</code>.</dd>
<dt>period</dt>
<dd>Period column in <code>data</code>.</dd>
<dt>age_order</dt>
<dd>(Optional) Character vector giving the desired order of age levels.
If NULL and the <code>age</code> column is factor/character, uses <code>unique(sort(data[[age]]))</code>.</dd>
<dt>period_order</dt>
<dd>(Optional) Vector (numeric or character) giving the desired order of periods.
If NULL and <code>period</code> column is a factor/character, uses <code>unique(sort(data[[period]]))</code>.</dd>
<dt>M</dt>
<dd>Grid factor, defined as the ratio of age interval width to period interval width.
Defaults to 1 (i.e. assuming equal sized age and period increments).</dd></dl>
