Research: Mega Millions Simulation — Hot, Cold & Independence
Generated: 2025-12-15T20:19:15.533Z · Lottery: Mega Millions (sample)
Pre-registration
- Primary hypothesis: Under independence, conditioning on a lagging first block does not make the target appear sooner. (Δ = 0).
- Primary metric: Primary outcome = ΔmeanWaitToFirstHit (RMST@200) for lagging − control; one-sided direction = lagging sooner (Δ<0).
- Analysis plan: We report analytic 95% CIs for ΔRMST@200 (primary), plus secondary ΔmeanCount@10 and a bounded ΔpHitWithin(X) using a scenario-specific X chosen to avoid ceiling/floor (baseline near ~0.7). We also show a robustness grid over (cutoff, window, alpha).
Design
- Mode: target
- Rules: main 5 of 70
- Seed: 1; Future draws: 200; Grid trials per cell: 2000
- Primary horizon (RMST): 200; Secondary meanCount window: 10
- Grid: cutoff ∈ {50, 100, 200}, windows ∈ {5, 10, 20, 50, 100}, α ∈ {0.01, 0.05}
- UX pHitWithin window: 16
- Target mode: random
Primary result (pre-registered)
Mode: target; cutoff=100; alpha=0.05; window=10; RMST horizon=200
Primary outcome: ΔmeanWaitToFirstHit (RMST@200) lagging − control
Definition: draw index of first hit in the future window (1..T), with “no hit” treated as right-censored at T; reported as RMST = E[min(Tfirst, T)].
Estimate: 4.660
95% CI: -0.491 to 9.811
One-sided p (approx): 0.961905
n: lagging=46; control=1939
Note: p-value is one-sided because direction (lagging sooner ⇒ Δ<0) is pre-registered; CIs are two-sided 95%.
Censoring rate: lagging=0.000000; control=0.000000
Secondary outcome: ΔmeanCount in next 10 draws (lagging − control)
Estimate: -0.232
95% CI: -0.444 to -0.021
(Linear expectation metric; not bounded by 0..1.)
Tertiary (bounded / UX metric): ΔpHitWithin(16) lagging − control
Window is chosen to avoid ceiling/floor when possible; still bounded and non-linear.
Estimate: -0.110826
95% CI: -0.254578 to 0.032926
Kaplan–Meier survival curve: probability the target has nothit yet by draw t
Curves should overlap under independence; systematic separation would indicate a real shift in time-to-first-hit.
Interpretation: Lagging numbers do not reach their first hit sooner than comparable non-lagging numbers under independence. Shaded areas represent pointwise 95% confidence intervals.
Limitations
- Simulation-based
- Assumes independence
- Not testing real-world rigging
Data verdict (plain language)
Verdict: No evidence of a ‘due’ effect.
- ΔRMST@200 = 4.660 (95% CI -0.491 to 9.811); one-sided p≈0.961905. Estimate is slightly later, but not reliably different from 0.
- Interpretation: “Lagging sooner” means fewer expected draws until first hit (negative ΔRMST).
Power / sensitivity (approx)
Approximate minimal detectable effect (80% power; normal approximation; two-sided alpha). Approximate also because the cohort is defined by a binomial-tail conditioning event.
Primary metric baseline meanWait (RMST@200): 13.905
n: lagging=46; control=1939
MDE @80% power(|ΔmeanWait|): 7.358
Secondary baseline meanCount@10: 0.711
MDE @80% power(|ΔmeanCount|): 0.302
Interpretation: effects smaller than the MDE are hard to reliably detect with this cohort selection + sample size.
“Approximate” reflects both the normal approximation and the binomial-tail conditioning used to define cohorts.
Tertiary metric baseline: pHitWithin(16) = 0.697782 · MDE @80% power (|ΔpHit|) = 0.191818
Interpretation notes (important)
- Independence null: for toy processes (coin/die) the true effect is 0 by construction; any single “significant” result can occur by chance when you scan many cells.
- Ceiling/floor risk: when baseline pHitWithin is near 1 (ceiling) or near 0 (floor), ΔpHitWithin is a bounded, non-linear metric and can look more dramatic than it is.
- Preferred quantity: the primary endpoint here is mean wait-to-first-hit (RMST@T), which directly targets “does it show up sooner?” and avoids the ceiling pathology of pHitWithin in high-p regimes.
- Small cohorts: grid cells with very small cohort sizes (n <20) are shown for completeness but are not interpretable (often producing degenerate CIs like 0 to 0).
What these results do not show
- No “compensation” mechanism: a cold streak does not create a forward advantage under independence.
- No exploitable strategy: statistically significant cells (especially under ceiling/floor metrics or small n) do not imply predictability or an edge.
- No jackpot implication: this does not change the combinatorial odds of a specific full ticket.
- No claim about real-world fairness: real lotteries can be tested for bias separately; this report’s main claim is about conditional reasoning under the null.
Robustness grid (lagging vs control)
- Each row is one (cutoff, α, window). Look for systematic drift away from 0; do not over-interpret isolated “significant” rows.
- Rows with n(lag) or n(ctrl) < 20 are visually muted and are not interpretable.
