Comparison of three major meta-analytic approaches

Blair T. Johnson, Brian Mullen, Eduardo Salas
1995 Journal of Applied Psychology  
Three major meta-analytic approaches have been developed and applied to integrate empirical research.  ...  A comparison of their statistical formulas suggested that they should yield different answers to the meta-analytic questions of central tendency, variability, and prediction by moderators.  ...  Comparison of Statistical Formulas to Answer Analytic Questions On some of the three meta-analytic tasks, the three general approaches provide an apparently equivalent solution, including especially the  ...

Data Cleaning

Xu Chu, Ihab F. Ilyas, Sanjay Krishnan, Jiannan Wang
2016 Proceedings of the 2016 International Conference on Management of Data - SIGMOD '16  
Detecting and repairing dirty data is one of the perennial challenges in data analytics, and failure to do so can result in inaccurate analytics and unreliable decisions.  ...  While traditionally such approaches are distinct from quantitative approaches such as outlier detection, we also discuss recent work that casts such approaches into a statistical estimation framework including  ...  "For Statistics" are the ones that are explicitly designed to support data cleaning for aggregate analytics and advanced statistical analytics.  ...

A Rebuttal to Borchgrevink's Criticism of Our Meta-Analytic Recommendations

Michael Lynn, Brian Mullen
1998 Journal of Hospitality & Tourism Research  
Borchgrevink presented flawed arguments against our (Lynn & Mullen) previous recommendation that hospitality researchers employ meta-analytic techniques other than those of Hunter and Schmidt.  ...  Conclusions Borchgrevink's (1998) defense of the Hunter and Schmidt (1990) meta-analytic techniques is flawed.  ...  However, the major purpose of our original article was not to criticize Hunter and Schmidt but to promote the use of meta-analysis in hospitality research.  ...
