I have a simple question, but I couldn't find the answer in R manuals. Assume I have a list: > foo <- list() > foo[[1]] <- c(1, 2, 3) > foo[[2]] <- c(11,22,33) > foo[[3]] <- c(111,222,333...

Dear Experts, In metafor's multivariate specification (which gives control over the `struct` argument), apparently there is a requirement for the variable appearing on the left-side of `|` to only be a categorical factor. First, why is this required conceptually...

I was wondering if anyone had some sample time series dgp code. I am particularly interested in examples of autoregressive processes and error correction model DGPs. I have attached a more specific example of what I mean. I have tried...

Version 0.99-0 of the proftools package for analyzing and visualizing R profiling data has been uploaded to CRAN. This is a major update that adds new summary functions, new and improved visualizations, and tools for subsetting and filtering...

Hello All, A quick question. I have some labs that have conducted multiple studies each targeting several outcomes, like: labID studyID outcomeID 1 1 1 1 1 2 1 2 1 1 2 2 2 1 2 2 1 3...

Dear Meta Experts, (A) My understanding has been that the sandwich estimators are only relevant to rma.mv() models where the structure of `V=` and/or `random=` is suspected to be misspecified (hence SE of fixed effects may be inaccurate...

Dear Colleagues, Imagine I have two models. Model 1: random = ~1 | study / row_id Model 2: random = ~ row_id | study, struct = "CS" I understand that the diagonal elements of the variance-covariance matrix of a study with two effect size...

Dear R users, My input is a matrix. The matrx rows are sample; the matrix columns are features. I need an output matrix which include the original features and some kinds of transformed features. For example, there are only three...

Hello All, Imagine a single-group experiment (same group pre- and post-tested) has been replicated ten times with independent groups of participants by the same lab: R O X O ==> 10 times In each experiment, participants answer a multiple...
