Extracting draws from posterior after using emmeans and hpd.summary

Asked 2022-Feb-14 at 22:54

I have a dataset from participants that provided liking ratings (on a scale from 0-100) of stimuli associated with rewards of different magnitudes (factor pval, with levels small/medium/large) and delay (factor time, with levels delayed/immediate). A subset of the data looks like this:

Regarding the first question: As is true of most summary methods, the returned object is just a summary, and it doesn't contain the information to convert it back to an object like the one that was summarized. However, the original emmGrid object does have all the needed content.

The other barrier is trying to work from the contrasts you don't want rather than getting the ones you do want. It is usually best to do the means and contrasts in two separate steps. It is quite simple to do:

ANSWER

Answered 2021-Jan-21 at 11:38

It turned out that the discrepancy was arising due to seed setting not being honored by brms::posterior_predict

Upon discussing with developer of brms package in github, he root caused the issue to be the following:

If you have set options(mc.cores = ), posterior_predict will evaluate in parallel by default, unless you change the core argument. On windows, parallel execution is done via parallel::parLapply and I don't know how that function respects seeds, if at all. When executing the code in serial (with 1 core) the results are reproducible.

Once I set the mc.cores to 1, I no longer see the discrepancy between posterior_predict and add_predicted_draws.

Hence I am marking the issue as resolved.

QUESTION

Caterpillar plot of posterior brms samples: Order factors in a ggdist plot (stat_slab)

Asked 2020-Sep-10 at 02:52

I ran a bayesian linear mixed model with brms and can plot the estimates nicely but I can't figure out how to order the single-subject estimates based on the mean of the posterior samples (so as to get a caterpillar plot). This is what I've done.

Two points for consideration:

Ungroup the result from spread_draws, otherwise you won't be able to reorder the levels of subject;
Use fct_reorder from the forcats package in tidyverse. It's designed for this exact purpose.

Your plot looks fine and gives me the following output. I am running R 4.0.2 and RStudio version 1.2.5 on windows. However, my output looks like yours if I expand it horizontally.
