as_strata

<p>Collapse multiple categorical variables into distinct unique categories.
e.g.</p>
<p><div class="sourceCode"></div></p><pre><code>as_strata(c(1,1,2,2,2,1), c(5,6,5,5,6,5))
</code></pre><p></p>
<p>would return</p>
<p><div class="sourceCode"></div></p><pre><code>c(1,2,3,3,4,1)
</code></pre><p></p>

Implements standard and reference based multiple imputation methods for continuous
longitudinal endpoints (Gower-Page et al. (2022) <doi:10.21105/joss.04251>). In particular,
this package supports deterministic conditional mean imputation and jackknifing as described
in Wolbers et al.  (2022) <doi:10.1002/pst.2234>, Bayesian multiple imputation as described
in Carpenter et al. (2013) <doi:10.1080/10543406.2013.834911>, and bootstrapped maximum
likelihood imputation as described in von Hippel and Bartlett (2021) <doi: 10.1214/20-STS793>.
