Effects of Proximity to Delta Ponds City Park on Real Home Prices
Bibliographic record
Abstract
in partial fulfillment of the requirements for honors in Economics. Abstract: Hedonic studies consistently find that single family homes within close proximity to parks and green spaces command higher prices, all else held equal. We use hedonic price theory and robust regression to estimate the effects of proximity to Delta Ponds City Park on the real prices of single family homes for the years 2000 through the first quarter of 2012. The goal is to discover if recent investments in the park made by the City of Eugene and its partners were valued by the citizens of Eugene, as reflected by an increased willingness to pay for living arrangements closer to the park. We find that investments increased home values for houses which sold for $247,000 dollars or more. Additionally, we found no measurable effects in the Willakenzie Neighborhood, who gained easy access to the park after the construction of a pedestrian bridge in November 0f 2011.

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.
