Abstract

fetched live from OpenAlex

This paper develops a conceptual framework resulting in an alternative method for selecting principal variables for computing a Water Poverty Index (WPI) at the national scale. To this end, a principal components variable selection strategy is applied to the 2002 data obtained for 147 countries on five key components- resource, access, capacity, use, and environment- compiled by Keele University. The results suggest that only three components (i.e., access, capacity, and environment) with different weights (i.e., the highest weight to capacity and the lowest weight to environment) be used for WPI calculation. It also turns out that a simpler index, based on two components (i.e., capacity and environment) with equal weights, can be computed with little information loss. The new WPIs, which are shown to correlate well with two well-known socioeconomic indicators, could help government, non-government, and business organizations set priorities for communities and countries of greatest resource needs.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
