fe8187b72f Add robustness checks: wild cluster bootstrap and distributed lag
- Insert Robustness Checks section before Hypotheses Summary
- Wild cluster bootstrap (B=999 Rademacher) addresses G=13 small-cluster problem
- Distributed lag model tests 1-year delayed budget effects (2017-2023 sample)
- Update Data & Methods to describe both robustness checks
- Update Results to reference bootstrap and distributed lag findings
- Fix duplicate robustness paragraph that was appended twice

98f48652b1 Update write-up cells to reflect 2025 inspection data
- Data & Methods: panel is now 130 obs (13 districts × 10 years);
  regression sample remains N=104 (2016-2023); right-censoring caveat added
  for 2025 enforcement metrics
- Analysis: clarifies 2025 descriptive-only status and right-censoring issue
- Results: Table 1 extended through 2025 with 2024/2025 footnotes; narrative
  updated to note compliance peak (92.6% in 2024), slight 2025 dip (90.5%),
  and right-censored resolution/enforcement metrics for 2025

fff3019e27 Extend inspection/violation data through 2025
- SQL year filters: BETWEEN 2016 AND 2025
- is_budget_year flag: year >= 2024 (covers both 2024 budget estimate and
  2025 where no budget data exists) — both excluded from regressions
- Data & Methods and Analysis cells updated to reflect 2016-2025 data range
  with 2016-2023 as the regression sample

365bbe570a Add journal-quality Data & Methods, Analysis, and Results write-up cells
Three markdown cells written in PAR/Policy Studies Journal style:
- Data and Methods: sources, sample, variables, model equations
- Analysis: analytical strategy and identification rationale
- Results: full findings with formatted tables for all four hypotheses

9d18c02105 Fix display_cols to detect summary2 column names dynamically
statsmodels uses z/P>|z| instead of t/P>|t| with cluster-robust SEs
in some versions. Auto-detect from the actual table columns.

8038a3fab4 Initial commit: texas inspection expenses analysis notebook
Jupyter notebook analyzing RRC budget (2016-2024) against inspection/violation
outcomes across Texas RRC districts. Tests four hypotheses: organizational
capacity, goal ambiguity, district multilevel effects, and spatial factors.
