Pull request overview
This PR adds comprehensive scientific experimentation capabilities to ExperimentFramework through two new packages (ExperimentFramework.Data and ExperimentFramework.Science). The implementation provides rigorous A/B testing infrastructure with proper statistical methods, power analysis, effect size calculation, and publication-ready reporting.
Key changes include:
- Statistical testing framework (t-test, chi-square, Mann-Whitney U, ANOVA)
- Effect size calculators with confidence intervals (Cohen's d, odds ratio, relative risk)
- Power analysis and sample size calculation
- Multiple comparison corrections (Bonferroni, Holm, Benjamini-Hochberg)
- Thread-safe outcome data collection and storage
- Hypothesis builder with pre-registration support
- Publication-ready report generation (Markdown and JSON)
