metasens: Brief overview of methods and general hints

Description

R package metasens provides advanced statistical methods to model and adjust bias in meta-analysis and supports Schwarzer et al. (2015), Chapter 5 "Small-Study Effects in Meta-Analysis" https://link.springer.com/book/10.1007/978-3-319-21416-0.

Details

R package metasens is an add-on package for meta providing the following meta-analysis methods:

• Copas selection model (function copas) described in Copas & Shi (2001) and evaluated in Schwarzer et al., 2010);

• limit meta-analysis (limitmeta) by Rücker et al. (2011);

• upper bound for outcome reporting bias (orbbound) described in Copas & Jackson (2004);

• imputation methods for missing binary data (metamiss) described in Gamble & Hollis (2005) and Higgins et al. (2008).

Furthermore, functions and datasets from metasens are utilised in Schwarzer et al. (2015), Chapter 5 "Small-Study Effects in Meta-Analysis", https://link.springer.com/book/10.1007/978-3-319-21416-0.
