This reproducible R Markdown analysis was created with workflowr (version 1.7.2). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.


Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.

Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.

The command set.seed(20260831) was run prior to running the code in the R Markdown file. Setting a seed ensures that any results that rely on randomness, e.g. subsampling or permutations, are reproducible.

Great job! Recording the operating system, R version, and package versions is critical for reproducibility.

Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.

Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.

Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.

The results in this page were generated with repository version 588e463. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.

Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:

This website documents the data, statistical analyses, and publication outputs for a multi-country study of excess mortality during the COVID-19 pandemic. The repository contains the exact source snapshots used for the analysis and separates computationally intensive model fitting from lightweight reporting.

Manuscript figures and table

Each page provides the manuscript caption, the code used to construct the publication artifact from precomputed analysis results, and downloadable output.

Publication item Description
Figure 1 Seasonally Adaptive Mortality Model illustration
Figure 2 Initial- and Delta-wave P-scores in Europe
Figure 3 Initial- and Delta-wave P-scores in North America
Figure 4 P-scores by vaccination group over time
Figure 5 Female-minus-male P-score differences over time
Table 1 Wave-specific P-scores for selected regions

Regional analyses

The regional analyses page maps the common estimands to the source-specific pipelines for Europe, England and Wales, Ireland, Canada, and the United States. The statistical methods page records the shared model and summary definitions.

Supplementary analyses

The supplementary overview provides a frozen inventory, summary definitions, and complete downloads. Interactive pages expose geography-specific mortality and P-score time series and all four wave-specific map summaries without loading posterior draws or fitted model objects in the browser.

Reproducibility

Exact reproduction uses the versioned files under data/raw/. Provider-hosted data may subsequently be revised; the optional access scripts retrieve current versions without replacing the repository snapshots. See data sources and reproduction instructions for details.

Model fits and posterior draws are intentionally excluded from Git because they are large and computationally expensive to recreate. Website generation reads the tracked publication figures and table and does not refit any model.
