科学领域:

生物信息学是一种生物信息学.
统计遗传学统计遗传学
计算生物学计算生物学

背景情况:

跨研究的可复制信号加强了科学证据.
高通量实验产生大量的数据,需要强大的分析方法.
空间转录组研究提供了对组织组织和细胞功能的洞察.

研究的目的:

介绍STAREG,一种用于高通量实验中的可复制性分析的新型统计方法.
将STAREG应用于空间转录基因数据集,以识别强大的生物信号.
在多项研究分析中增强统计能力并控制错误发现率 (FDR).

主要方法:

STAREG模拟了多项研究中p值的联合分布,并考虑到异质性.
使用来自高通量实验的总结统计数据.
使用预期最大化 (EM) 算法和池相邻违规者算法 (PAVA) 来实现可扩展性.
