[R-meta] Publication bias/sensitivity analysis in multivariate meta-analysis

[James Pustejovsky]

Hi Huang,

Here are two recent studies on methods for detecting small-study effects
and other forms of publication bias in multivariate meta-analysis:

* Hong, C., Salanti, G., Morton, S., Riley, R., Chu, H., Kimmel, S. E., &
Chen, Y. (2018). Testing small study effects in multivariate
meta-analysis. *arXiv
preprint arXiv:1805.09876*. https://arxiv.org/abs/1805.09876
* Rodgers, M. A., & Pustejovsky, J. E. (In Press). Evaluating Meta-Analytic
Methods to Detect Selective Reporting in the Presence of Dependent Effect
Sizes. Psychological Methods, forthcoming.
