Tools for Creating, Updating, and Analyzing Survey Replicate Weights

github.com/bschneidr/svrep ↗

Steadily absorbing every replicate-weight method the survey literature has to offer

survey-statisticsreplicate-weightsvariance-estimationbootstrapapi-consolidation
◆Current state
svrep is a broad implementation of replication-based variance estimation for complex surveys, covering the generalized bootstrap, Fay's generalized replication, successive difference replication and the random-groups jackknife. The last two years added methods quickly: the Antal-Tille doubled half bootstrap, the Beaumont-Emond and kernel-based BOSB variance estimators, and optional torch-backed computation of replicate weights. Version 0.9.0 tightened the package boundary, promoting 'survey' from Imports to Depends and deleting the long-deprecated rescale_reps().
◆Where it's heading
The recent arc is consolidation rather than expansion. 0.9.0 removed a deprecated function, added accessors and refactored for memory, while 0.9.1 exists only to answer a Journal of Statistical Software review. That submission explains the shape of the changelog: the API is being frozen and documented rather than extended. Method coverage is broad enough that additions are now gap-fills for particular sampling designs.
◆Prediction
Expect the next releases to track the JSS review through to publication with documentation and output-structure tidying, and any new estimator to arrive only when an issue or reviewer asks for a specific design.

    Documentation and output tidying for JSS review

    A patch cut purely to answer the Journal of Statistical Software editorial team: a documentation note about which bootstrap-sizing function has a plot method, and a simplified output object from estimate_boot_reps_for_target_cv(). No statistical behaviour changes.

    'survey' moves to Depends; deprecated rescale_reps() removed

    The clearest boundary-setting release in the package's history: 'survey' is attached whenever svrep loads, the deprecated rescale_reps() is finally gone, and get_rep_scale_coefs() and get_rep_type() give users a supported way to read design metadata. Fits the consolidation phase — the surface is being tidied, not widened.

    Antal-Tille doubled half bootstrap added

    Adds the doubled half bootstrap for single-stage designs, whose practical draw is that it produces integer replication factors. Another entry in the steady accumulation of published replication methods rather than a change of direction.

    Successive difference replication, kernel variance estimator, optional torch backend

    The densest release in the window: successive difference replication, the Breidt-Opsomer-Sanchez-Borrego kernel estimator for finely stratified samples, Beaumont-Emond, and an optional torch backend for building replicate weights. The torch option is the first sign that weight-matrix size, rather than method coverage, is the binding constraint for some users.

    Helpers to shuffle, subsample and pad replicate columns

    Adds shuffle_replicates(), subsample_replicates() and add_inactive_replicates() — plumbing for users assembling replicate sets independently across strata. Practical rather than statistical, and typical of how this package fills the gaps its users actually hit.

    Version bump for CRAN check failures

    A CRAN-driven bump with no user-facing change, alongside removal of unmarked UTF-8 strings and LaTeX formatting that broke manual builds on an older macOS release. Housekeeping between substantive versions.
