Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Regression-based XGBoost achieves higher average QWK (0.475) than classification XGBoost (0.458) for speech scoring on the SOPI dataset. → Pakhi Bamdev 2023

Model comparison on the SOPI test split across six prompts, reported in the Results section. Regression XGBoost achieved "an average QWK of 0.475, r of 0.493, and MSE of 0.299"; classification XGBoost averaged QWK 0.458, r 0.484, MSE 0.333.

"On comparison, we notice that for regression analysis, XGBoost outperforms every other model by achieving an average QWK of 0.475, r of 0.493, and MSE of 0.299 across all the six prompts."
