Key Findings

Methodology

The Dice Roll Method uses a temperature-scaled nucleus sampling model to decompose response variance into sampling, prompt phrasing, run-to-run, and model version components. It employs a negative-binomial mixed model, Cliff's δ, dependence-preserving bootstrap, simulation-based power analysis, and generalizability theory decomposition to reanalyze five brand recommendation auditing studies.

Key Results

  • Result 1: From the D-study, exploratory (n=5, G=0.58), confirmatory (n=10, G=0.74), and rigorous (n=15, G=0.81) iteration guidance tiers emerge, tied to effect size and generalizability coefficients.
  • Result 2: The four metric families (count, set, embedding, fairness-adjusted PASOR) are complementary, motivating a compact metric battery over single indicators.
  • Result 3: Pre-registered external validation on three independent corpora reproduces the D-study reliability prediction in 37 of 39 cells with no failures, n=5 power value precise to two decimals.

Significance

This study provides a statistically principled foundation for repeated-query auditing of LLM brand recommendations, addressing the lack of standardized protocols in existing methods and ensuring reliability under the conditional dependencies and non-Gaussian structure of real autoregressive generation.

Technical Contribution

Technical contributions include combining the Dice Roll Method with a temperature-scaled nucleus sampling generative model, offering new variance decomposition and negative-binomial GLMM power analysis, replacing traditional normal-theory power tables.

Novelty

First to standardize the Dice Roll Method as a protocol for LLM brand recommendation auditing, providing a new methodological framework to address the arbitrariness in iteration counts and stability metric selection.

Limitations

  • Limitation 1: Fixed iteration tiers do not transfer, supporting a pilot-then-solve reading.
  • Limitation 2: All five reanalyzed datasets are prior studies by this research group, external validation is the next step.

Future Work

Future work includes external validation on independently collected data and exploring the applicability of the Dice Roll Method in other domains.

Plain Language Accessible to non-experts

Imagine rolling a die, each roll gives different outcomes. The Dice Roll Method is like rolling a die, auditing LLM brand recommendations through repeated queries. Each query is like a roll, results may vary, but through repetition, you get a more stable outcome. This method helps us understand the random variations in LLM brand recommendations and ensures reliability.

Hey, imagine playing a game where every time you press a button, different brand recommendations pop up on the screen. This change isn't because the game is broken, it's designed that way! The Dice Roll Method is like a game trick, by pressing the button (querying) multiple times, you can see the stability of brand recommendations. This way, you know which brands are always recommended and which just pop up occasionally. Cool, right?

Abstract

Background: Researchers increasingly use repeated identical prompts to audit stochastic variation in large language model (LLM) brand recommendations, yet no standardized protocol exists for setting iteration counts, selecting stability metrics, or establishing reliability thresholds. Objective: We formalize the Dice Roll Method as a reusable protocol for repeated-query auditing of LLM brand recommendations, grounded in a generative model of temperature-scaled nucleus sampling. Methods: Total response variance is decomposed into sampling, prompt-phrasing, run-to-run, and model-version components. The stack: a negative-binomial mixed model with iterations as repeated measures; Cliff's delta as the distribution-free effect size; dependence-preserving bootstrap; simulation-based power; a generalizability-theory decomposition; drift diagnostics on pinned snapshots. We reanalyse five brand-recommendation auditing studies: approximately 190,000 observations, 270+ brands, 6 languages, iteration counts 5 to 40. Results: Three tiers of iteration guidance emerge from the D-study: exploratory (n = 5, G = 0.58), confirmatory (n = 10, G = 0.74), and rigorous (n = 15, G = 0.81), tied to effect-size and generalizability targets. The four metric families (count, set, embedding, fairness-adjusted PASOR) are complementary, motivating a compact metric battery over single indicators. A pre-registered external validation on three independent corpora (Motoki et al., 100-round; Rozado, 24 models; llm-stability) reproduces the D-study reliability prediction in 37 of 39 cells with no failures and the n = 5 power value to two decimals; the fixed tiers do not transfer, supporting a pilot-then-solve reading. Conclusion: The protocol gives repeated-query auditing of LLM brand recommendations a statistically principled footing under the conditional, non-Gaussian structure of real autoregressive generation.
