Pipe-friendly bootstrapping with list-variables in #rstats

A few days ago, my package sjstats was updated on CRAN. Most functions of this package are convenient functions for common statistical computations, especially for (mixed) regression models. This latest update introduces some pipe-friendly bootstrapping-methods, namely bootstrap(), boot_ci(), boot_se() and boot_p(). In this post, I just wanted to give a quick example of these functions,

The focus was less on adding new functions; rather, I improved existing functions by adding new smaller and bigger features to make working with the package easier and more reliable.

Gender Effect in Conference Talks

I was searching in the arXiv repository for an interesting paper to read over the weekend, when I found this: "Studying Gender in Conference Talks -- data from the 223rd meeting of the American Astronomical Society". The title and figures caught my attention more than the subject of the conference, I've to confess. The plot below, taken from the...

Data, data, data

Having presented preliminary findings from a national sample of therapeutic communities in Brazil, I thought the Babbage's words fits like a glove for those criticizing quantitative approaches for policy evaluations: the "Errors using inadequate data are much less than those using no data at all” (Charles Babbage).

This posting begs an obvious question: how has the mood in Venezuela varied over time with respect to voting intentions for the two political blocs? Next, can we...

Venezuela’s 2015 Parliamentary Elections

To get an idea about the political climate over there, I've collected some polls available on the internet.

Beautiful table-outputs: Summarizing mixed effects models #rstats

The current version 1.8.1 of my sjPlot package has two new functions to easily summarize mixed effects models as HTML-table: sjt.lmer and sjt.glmer. Both are very similar, so I focus on showing how to use sjt.lmer here. Linear mixed models summaries as HTML table The sjt.lmer function prints summaries of linear mixed models (fitted with

sjmisc – package for working with (labelled) data #rstats

The sjmisc-package My last posting was about reading and writing data between R and other statistical packages like SPSS, Stata or SAS. After that, I decided to bundle all functions that are not directly related to plotting or printing tables, into a new package called sjmisc.
