Abstract

This paper introduces a novel statistical methodology integrating machine learning (ML) and Bayesian modelling to facilitate personalized prognostic predictions with application to oncology. Utilizing power priors, we construct 'patient-similarity embeddings' that identify localized patterns of prognosis. The methodology is applied to study the prognostic value of markers of anticancer immunity within the tumour microenvironment of nonsmall cell lung cancer while adjusting for established clinical characteristics. The method outperforms traditional regression and ML models, while accurately identifying subgroup patterns, thereby enhancing statistical inference and hypothesis testing.

患者相似性嵌入贝叶斯方法在预后生物标志物推断中的应用与胸部癌症免疫。
本文介绍了一种集成机器学习(ML)和贝叶斯模型的新型统计方法,以促进个性化预后预测并应用于肿瘤学。利用权力先验,我们构建了“患者相似嵌入”来识别局部预后模式。该方法用于研究非小细胞肺癌肿瘤微环境中抗癌免疫标志物的预后价值,同时根据已建立的临床特征进行调整。该方法优于传统的回归模型和ML模型,同时准确地识别子群模式,从而增强了统计推断和假设检验。

期刊介绍: The Journal of the Royal Statistical Society, Series C (Applied Statistics) is a journal of international repute for statisticians both inside and outside the academic world. The journal is concerned with papers which deal with novel solutions to real life statistical problems by adapting or developing methodology, or by demonstrating the proper application of new or existing statistical methods to them. At their heart therefore the papers in the journal are motivated by examples and statistical data of all kinds. The subject-matter covers the whole range of inter-disciplinary fields, e.g. applications in agriculture, genetics, industry, medicine and the physical sciences, and papers on design issues (e.g. in relation to experiments, surveys or observational studies). A deep understanding of statistical methodology is not necessary to appreciate the content. Although papers describing developments in statistical computing driven by practical examples are within its scope, the journal is not concerned with simply numerical illustrations or simulation studies. The emphasis of Series C is on case-studies of statistical analyses in practice.
