The Scientific Process

01

Evidence Synthesis

We don't start with intuition. We ingest multi-source data to define the baseline variance and identify statistical outliers.

02

Bayesian Prior Setup

Every experiment is contextualized with historical results to calculate the required sample size for significant results.

03

Validation Loops

Continuous monitoring of p-values and confidence intervals ensures we never call a winner prematurely.

// Bayesian A/B Test Validation
function calculatePosterior(alpha_prior, beta_prior, trials, successes) {
  const alpha_post = alpha_prior + successes;
  const beta_post = beta_prior + (trials - successes);
  return { alpha: alpha_post, beta: beta_post };
}

// Sample Size Determination (Power Analysis)
const power = 0.8;
const alpha = 0.05;
const effect_size = 0.02;
const required_n = calculateSample(power, alpha, effect_size);

console.log(`Experiment Validation Status: PASS`);
console.log(`Statistical Significance: 99.4%`);
