+==== 2022-10-15: Allowing $\tau^2$ to Differ Across Subgroups ====
+A while ago, I wrote up a little discussion on how comparing estimates of independent meta-analyses or subgroups [[tips:comp_two_independent_estimates|here]]. Part of this discussion touched upon subgroup analyses and two possible approaches thereof, one where we assume that the amount of heterogeneity ($\tau^2$) is the same within the various subgroups and one where we relax this assumption and allow $\tau^2$ to differ across groups. I now wrote up a more extensive discussion of this [[tips:different_tau2_across_subgroups|here]] where I also illustrate several different methods/models for conducting a subgroup analysis that allow the amount of heterogeneity to differ across the subgroups.
+==== 2022-10-07: Convergence Problems with the rma.mv() Function ====
+I already had written up a little [[tips:convergence_problems_rma|discussion]] of convergence problems that can arise when using the ''rma()'' (i.e., ''rma.uni()'') function (and some remedies to deal with them) previously. I have now added an analogous discussion for the ''rma.mv()'' function [[tips:convergence_problems_rma_mv|here]].
