rt，现在在看一篇计量方面的论文，里面在检验统计量的渐近展开（Asymptotic expansions of test statistics)部分提到了，“probabilitic embeddings”，数学知识有限，不理解是怎么回事，希望各位告知，谢谢！

其中，涉及到这个词的一句话是：

Our subsequent theoretical development relies heavily on the probabilistic embedding of the partial sum process constructed from the innovation sequence into a Brownian motion in an expanded probability space.
