el_extract_strata_factor

<p>Prefers strata already materialized in the <code>survey.design</code> object
(typically <code>design$strata</code>). When unavailable, attempts to reconstruct
strata from the original <code>svydesign()</code> call. When multiple
stratification variables are supplied, their interaction is used.</p>

Methods to estimate finite-population parameters under nonresponse that is not missing at
random (NMAR, nonignorable). Incorporates auxiliary information and user-specified response models,
and supports independent samples and complex survey designs via objects from the 'survey' package.
Provides diagnostics and optional variance estimates. For methodological background see
Qin, Leung and Shao (2002) <doi:10.1198/016214502753479338> and Riddles, Kim and Im (2016) <doi:10.1093/jssam/smv047>.
