This book describes multivariate analyses for several indices commonly used in meta-analysis, outlines how to do power analysis for meta-analysis, and examines issues around research quality and research design and their roles in synthesisPigott, Terri D....
Meta-analysis is a method of data analysis applied to summarizing research findings, both quantitative and qualitative summaries of individual studies. Rooted in the fundamental values of the scientific enterprise of replicability, causal and correlational analysis, it is useful for answering three general...
Objective: We review the state of the art in meta-analysis and data pooling following the evolution of the statistical models employed. Methods: Starting from a classic definition of meta-analysis of published data, a set of apparent antinomies which characterized the development of the meta-analyt...
对于传播学研究的主题,方法,理论的使用,数据的采集方法等趋势的综合分析(meta-analysis),在传播学的期刊中占据着稳定的地位(Rasha&Weaver,2003)~①.Trumbo(2004)~②对90年代8种大众传播期刊~③所采用的方法的分析表明,定量方法与定性方法的使用比例约为60:... 李贞芳,韦路 - "中国传播学论坛——和谐社会, 公民...
We discuss how meta-analysis, a method for synthesizing research findings, can meaningfully impact personnel selection practices. Specifically, we review important changes in professional and legal practices from the past 30 years resulting from meta-analytic findings. The implications of using meta-analy...

PART 1 Data Analysis Chapter 3: Labeling 在第二章中我们讨论了将非结构化数据转化为结构化数据的方法,并产生了一个矩阵X,在这一步非监督学习算法已经可以学习矩阵中的模式,比如判断是否可以聚类。另一方面,监督学习算法需要将X中的特征与标签或值y对应起来,从而使得隐藏的特征参与预测,下面介绍对金融数据打标签的...
We are very proud to launch Video-MME, the first-ever comprehensive evaluation benchmark of MLLMs in Video Analysis! 🌟 It includes short- (< 2min), medium- (4min~15min), and long-term (30min~60min) videos, ranging from11 seconds to 1 hour. All data are newly collected and annota...
