Using Stata with Statistics Canada data: Incorporating complex survey design into analysis
Bibliographic record
Abstract
Most Statistics Canada data are based on surveys with complex survey designs. To allow users to account for the survey design in their analyses, Statistics Canada generally provides both a probability weight and a set of survey bootstrap weights in the survey data files. This presentation will give an overview of how to use the survey commands in Stata to account for the complex survey design using the weights and bootstrap weights provided. It will also give some practical advice on using these elements with various surveys and some of the pitfalls to avoid.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
