{report} #rstats package version 0.6.2 is now on CRAN!

MANY bug fixes in this version! Including corrected duplicated text outputs and dramatic speed increases for brmsfit models (which used to refit the model entirely every time).

Alrighty, {easystats} users! 👋 Ever wonder how those neat tables magically appear in your R console, or even better, in your fancy #rstats Markdown and Quarto docs?

Well, most of the objects you work with in {easystats} are basically tables, i.e. a 2D matrix with columns and rows...
library(modelbased) data(penguins) model <- lm(body_mass ~ species * island, data = penguins) out <- estimate_means(model, c("species", "island")) # basic text output out # HTML in viewer pane, using the gt-package display(out, format = "html") # tinytable by defaults prints to the viewer pane, too, # but we change the default to markdown for the console here options(tinytable_print_output = "markdown") # nice markdown output in the console, including colored text! display(out, format = "tt", footer = "") |> tinytable::style_tt(i = 1:3, color = "#cc0000") |> tinytable::style_tt(i = 4:6, indent = 2, background = "#009900") |> tinytable::theme_markdown(ansi = TRUE)

Okay, so you've crunched your numbers and got some awesome statistical models? Sometimes, just knowing "X predicts Y" isn't enough to really get to the juicy bits. That's where the cool post-hoc stuff comes in – think estimated marginal means, contrasts, pairwise comparisons, or #marginaleffects.

I’m about halfway through this update (first 11 tutorials are done). I think they’re a lot better. Using a consistent @easystats.github.io workflow throughout will - I think - massively reduce the cognitive load for students. Looking forward to road testing in autumn term.

Probably no-one except me uses my R tutorials in their teaching, but if you do, I'm re-writing them over the next 6-9 months. My goal is to streamline them based on 5 years of using them in class, but if you have (polite) requests/suggestsions let me have them. www.discovr.rocks/discovr/

Improved support for the great {tinytable}📦 from @vincentab.bsky.social coming to the easystats packages! Use the `display()` method for different output formats of your tables - HTML, markdown, or - when `format = "tt"` a `tinytable` object that renders context-dependent.

Personally I prefer using datawizard::standardize(), and specifically using it *in the formula*.

So
mtcars$hp_z <- scale(mtcars$hp)
mpg ~ hp_z

Becomes
mpg ~ standardize(hp)

This solves both issues you raise in your post.

🆕 Introducing check_group_variation() in the {performance} #Rstats package! 🎉

This function makes it easy to checks if variables vary within or between levels of grouping variables.

Perfect for understanding and designing mixed models 🚀

For every (possibly) complex question, there's an clear and easy to communicate solution - if you go for predictions/marginal effects/(pairwise) comparisons/contrasts instead of trying to interpret coefficients. #easystats #rstats
strengejacke.de Daniel 🕹️ @strengejacke.de · May 6
Here's another example. Instead of running multiple models for each "factor contrast" of interest and look at regression coefficients, you can also specify these contrasts directly in {modelbased} or {marginaleffects} (modelbased is just a convenient wrapper around marginaleffects and emmeans)
library(easystats) # sample data data(contrast_example, package = "modelbased") # center predictor of interaction term, for consistent results contrast_example$score <- center(contrast_example$score) # model with default factor-contrasts model1 <- lm(outcome ~ score * tx, data = contrast_example) # create custom contrasts for the "tx" factor treat_vs_none <- c(-2/3, 1/3, 1/3) short_vs_long <- c(0, -1/2, 1/2) contrasts(contrast_example$tx) <- cbind(treat_vs_none, short_vs_long) # model with custom factor-contrasts model2 <- lm(outcome ~ score * tx, data = contrast_example) # see parameter "tx [treat_vs_none]", value 1.94 - we got this results # due to custom contrasts... model_parameters(model2) # instead of re-running the model each time with different contrasts, simply # formulate what you want to do as "comparison" (or "hypothesis" in # {marginaleffects}): we want to compare the average effect of short + long # treatment against no treatment. We find these coefficients in rows 2+3 # (short+long) and row 1 (none). estimate_means(model1, "tx") # we now formulate this as comparison estimate_contrasts(model1, "tx", comparison = "((b2+b3)/2) = b1") # marginaleffects equivalent marginaleffects::avg_predictions( model1, variables = "tx", hypothesis = "((b2+b3)/2) = b1" )
