WHAT IS INSIDE

A complete missing-data workflow.

The package connects missingness description, model specification, diagnostics, pooled inference, comparison, and sensitivity analysis in one reproducible report.

01

Audit what is missing

Summarize and visualize missing responses by variable, case, program group, study wave, and pattern.

02

State the assumptions

Distinguish MCAR, MAR, and MNAR without claiming that an observed-data test can prove the mechanism.

03

Specify chained equations

Use predictive mean matching, logistic regression, ordinal logistic regression, and passive interactions with a documented predictor matrix.

04

Diagnose the imputations

Review chain behavior, logged events, observed and imputed distributions, and impossible completed values.

05

Fit and pool the models

Pool longitudinal mixed and binary logistic models across 20 completed datasets using Rubin's rules.

06

Test sensitivity

Compare complete cases and examine delta adjustments when departures from MAR could alter the conclusion.

DESIGNED FOR DOCTORAL RESEARCH

Use it when incomplete data are part of the methodological argument.

This workflow is useful when:

  • Your predictors, outcomes, auxiliaries, or repeated measures contain missing values.
  • Your dataset mixes continuous, binary, and ordinal variables.
  • You need to explain why variables entered the imputation model.
  • You need pooled regression estimates rather than one filled-in dataset.
  • Your committee expects diagnostics, a complete-case comparison, or sensitivity analysis.

Many irregular occasions, complex survey designs, survival outcomes, three-level data, or strongly MNAR processes require extensions beyond this introductory workflow.

THE DOWNLOADABLE PACKAGE

Run the example.
Then adapt your study.

The synthetic longitudinal dataset contains documented intermittent gaps and monotone attrition across continuous, binary, and ordinal variables. The complete analysis runs before you introduce your own data.

  • Editable R Markdown source and rendered report
  • Reusable missing-data functions for other projects
  • Documented longitudinal synthetic dataset
  • Package installer and RStudio project
  • Missingness tables and accessible figures
  • Methods and predictor-matrix exports
  • Pooled mixed and logistic model results
  • Complete-case comparison and delta sensitivity analysis
  • Start guide, integration plan, and individual license

The workflow supports analysis and documentation. Missing-data assumptions and model choices remain the researcher's responsibility and should be reviewed with the dissertation advisor, committee, or a qualified statistician.
