Meta-analysis is widely used to summarize estimated effects sizes across multiple statistical tests. Standard fixed and random effect meta-analysis methods assume that the estimated of the effect sizes are statistically independent. Here we relax this assumption and enable meta-analysis when the correlation matrix between effect size estimates is known. Fixed effect meta-analysis uses the method of [Lin and Sullivan (2009)](https://doi.org/10.1016/j.ajhg.2009.11.001), and random effects meta-analysis uses the method of [Han, et al. 2016](https://doi.org/10.1093/hmg/ddw049).
