Abstract

fetched live from OpenAlex

Abstract Census data has been widely used for community evaluation based on demographic and socioeconomic variables. However, the analysis is typically associated with specific areal units and the results often change when the size of the census configuration changes leading to scale distortions. Various approaches such as optimal zoning systems and multivariate statistical analysis have been developed to address the scale problem. But limitations in these approaches have led to the use of non-statistical methods to tackle the scale problem. This study combines a non-statistical method with descriptive statistical measures to develop a rough sets approach to constructing a census-based deprivation index (DI) and to determine its relationship to a recent immigrant population using the 2001 Canadian census. Application of the approach in the Greater Vancouver Regional District shows that rough sets can stabilize relationships for spatially grouped census data by mini-mizing scale distortions. Scale sensitivity measures are also estimated to translate DI relationships across three census configurations. The rough sets approach is suitable for areal data analysis because it is resistant to nonlinearity, outliers, and assumes no prior relationship between variables.

Not 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.
