How this prediction was made
- Baseline . Most recent borough result (2024-05-02)
- BES MRP Prior . Baseline blended with BES Wave 1-30 east_of_england prior (weight 15%, n=3761 regional respondents)
- National Swing (STM) . Strong Transition Model: multiplicative bounded swing, dampened by 0.1 for local
- Demographics . 1 demographic factor(s) applied
- Incumbency . No current holder data available
- New Party Entry . Reform UK has existing baseline, no proxy needed
- Normalise . All shares scaled to sum to 100%
- Restrict to ballot . Removed 3 party/parties not standing in 2026 (SNP 0.1pp, Plaid Cymru 0.0pp, Other 0.0pp). Their share redistributed pro-rata.
- 2025 county-cycle anchor . Blended (weight 0.1) toward May 2025 results for hertfordshire (78 divisions, 285,843 votes), adjusted by national swing since May 2025. This corrects the model's tendency to under-weight Reform's 2025 county breakthroughs in 2-tier districts.
- National-share calibration . Aggregate-predicted vs national-polled mismatch corrected at strength 0.65. Multipliers — Labour ×0.82, Conservative ×1.00, Reform UK ×1.15, Liberal Democrats ×0.96, Green Party ×1.12, SNP ×1.00, Plaid Cymru ×1.00.
