What validation tests are useful in confirming results?
Time-series CV (10 folds), 78 pairwise Diebold-Mariano (all p<0.001), ANOVA (F=47.89), bootstrap (2000), Monte Carlo (100 runs).
Key Takeaway
Validation: temporal CV, 78 pairwise tests, bootstrap, Monte Carlo robustness.
Detailed Explanation
The results are statistically validated rigorously: **Time-Series Cross-Validation:** Expanding window CV (10 folds, data from 2000 to 2019) proves out-of-sample forecast accuracy and eliminates overfitting artifacts. Statistics from 78 pairwise comparisons between the ENSM and 17 baselines, the MAPPO and 12 baselines, integrated and decoupled, and integrated and 48 algorithm-combinations indicate statistically significant differences (all p<0.001), establishing that the superiority of the proposed framework is not due to chance. One-way ANOVA on algorithm family (F=47.89, p<0.001) rejects null hypothesis of equal performances, followed by post-hoc Tukey HSD tests confirm MAPPO outperforms the rest of the alternatives, while controlling for the family-wise error rate. Non-parametric alternative to paired t-test (accounts for non-normal distributions) confirms ENSM>baselines (W=342, p<0.001, effect size r=0.72, large effect). Bootstrap resampling consist on 2000 resampling (resampling on forecast errors and RL rewards) generate empirical confidence intervals for all reported metrics. Execute Monte Carlo robustness check by running the scenario 100 times with stochastic perturbations on parameters. Demand is perturbed between -20% and +20%, cost between -30% and +30%. The solution is said to be robust if the coefficient of variation is less than 2% for share of renewables and less than 5% for investment. Convergence testing refers to the monitoring of RL training curves to ensure they have a stable convergence (no oscillations after the convergence) and to confirm the reproducibility of the RL agent with 100 independent training runs (σ=0.012 reward variance). As described above, these validation procedures meet the NeurIPS/ICML reproducibility standards or exceed it and make the validation scientifically sound.
