berndweiss/tuma: tuma - A graphical user interface for teaching univariate meta-analysis

This package provides a graphical user interface (GUI) to visualize univariate fixed effect (FEM) and random effects model (REM) meta-analysis. By interactively manipulating effect sizes and standard errors, it is possible to better understand their relationship with summary (FEM and REM) and heterogeneity related statistics (Q, I^2 and tau^2). Additionally, two plots are created which show a typical forest plot as well as a density plot with N(hat{theta}, tau^2). These plots also change if the individual effects sizes or standard errors are manipulated. This work was supported by a fellowship within the "Postdoc-Programme" of the German Academic Exchange Service (DAAD).
