Original collectionUnder development

Under development — library extension. This report is part of the expanded-library work, not the original collection. Source preparation, methods and results are subject to revision.

Provisional eligibility assessment — under development. The target is a temperature response curve represented by eleven temperature-bin indicators. A vector of dose bins is not a binary treatment, and games are not absorbing policy adopters. This working assessment is not fully vetted and may change.

Under development — community extension. This is a provisional source-design assessment, not a new successful replication or a final eligibility ruling.

Source design and template applicability

The target is a temperature response curve represented by eleven temperature-bin indicators. A vector of dose bins is not a binary treatment, and games are not absorbing policy adopters.

No DiD estimates, uncertainty intervals or homogeneity-test decision were computed in this tranche. No point is added to the calibration plots. This is not a zero effect or a failed statistical test.

Recorded treatment-column measurement

96,231 distinct nonmissing values in wtemp_avg.

Observed support in the indicated source frame; missing values excluded. N=132,649; missing=1,658. Frame: selected_source_data. Source: /Volumes/LAL_BAK/did-cardinality-work/packages/Kuruc_LoPalo_O_Connor_AEJ-Applied_2024_192427/WtPCoolerDay/analysis/data/retro_weather2.csv.

These are the existing data-measured counts, not counts inferred from design labels. A binary instrument, group indicator or interaction component need not be the treatment of interest; the source-design assessment above takes precedence for template applicability.

Replication status

This tranche: unsupported design; source code/documentation inspected, no estimator run.

Supplied library: verified; verification: verified; preparation: runs_with_shim. These are the library’s labels, not new verification claims. Missing data and unsupported designs are separate issues.

Evidence and provenance

The following files in the supplied library were inspected. Their SHA-256 digests are recorded in the downloadable assessment JSON. Source archives and microdata are not redistributed.
