Leveraging HTE Data Structure
The paper emphasizes that HTE datasets possess a specific structure that, if overlooked by generic ML/AI algorithms, can lead to misleading conclusions. It advocates for leveraging knowledge about the data-generating process using a statistical model for reliable, interpretable insights.
Novel Generalized Linear Model
Introduces a generalized linear model using a continuous Bernoulli distribution for reaction yields, addressing the non-normal, bounded, and skewed nature of yield data. It employs a four-way analysis of variance framework with strong heredity constraints to manage parameter identifiability and chemical realism.
Interpretable Mechanistic Understanding
The estimated model provides interpretable parameters for main effects and interactions (e.g., additive-halide), offering deeper insights into Buchwald-Hartwig amination mechanisms. Key findings include the significant influence of halides and the nuanced, context-dependent roles of additives.

Case Study: Buchwald-Hartwig Amination
The Buchwald-Hartwig amination dataset serves as a complex and illustrative case for this methodology. The model successfully identifies key factors influencing reaction yield, such as the significant impact of halides on oxidative addition and the nuanced roles of additives in stabilizing or destabilizing catalytic intermediates. The study confirms that even minor structural differences in additives can drastically alter reaction efficiency when combined with specific halides, providing a general chemical rationale for observed interaction signs and magnitudes. This approach leads to chemically meaningful hypotheses and guides future experimentation.
