9 FLAWS of ‘Summary’ Function You DIDN’T Know About and How to Fix Them

Exploring how one categorical predictor affects a numeric outcome is another way of saying - we’re comparing several groups. While ANOVA is a common approach, simple linear regression delivers more insights. Expect to learn how to maximize inference from your model, why famous “summary” function does’t provide a good summary and what are the best alternatives for it.

    Thanks a million for this super-helpful video. I learned about the emmeans package feom your emmeans video and i was blown away. Academic publications usually don't include the means of each category and i dont know why it's NOT required. I recently published a paper using emmeans to show the group estimated averages based on the model and i got a lot of push backs. Please, when you're able to get to it and if it interests you, could you please review ggpredict, ggemmeans and emmeans, their similarities and differences and when appropriate to use one or the others. Thank you.

    that's an a great idea! I do usually compare those functions and most of them use emmeans in the background. For instans, ggemmeans and tbl_regression with contrasts all use emmeans. So, getting back to the sorce - emmeans is the way to go. The results could be tricky though, because the gtsummary never say it uses Tukey correction by default, so the results were strangely different from the summary and co. But yeah, thanks for the suggestion, I'll consider to build them into the next videos and thanks for watching and commenting, this is the best support!

    oh, and by the way, I do publish a lot of academic papers where I use contrasts and I usually use prediction plots (effect plots) + the table with contrasts and it usually has no problems with reviewers. The pushback happens sometimes when you hit an old reviewer, who used the same sh...t the whole life and thinks he/she known everything better. just politely ignore and continue to contribute to science ... that's what I tell myself every time I get stupid requests, like ... why don't you just use ANOVA ... for everything. That really happens a lot!

    I just ran into the problem you described at the start of the video a few days ago...namely trying to report confidence intervals, interactions, and so on and was struggling to do so using only the summary function. Thank you so much for this video, it had some really great tips in there and you explain it so concisely and clearly that it actually becomes interesting (and I never thought I would say this about statistics to be honest :D). You're a natural teacher and i'm sure your work and effort is greatly appreciated, at least it is on this end! Thanks!

    Yes, I suppose we have all found using the summary function for models messy at some point (although R still makes it easy compared to other software). These "flaws" are common in learning, teaching, and even authoring, so hopefully we will not repeat them again. In fact, thanks to this video I am in the process of correcting them in my current R project. PS: Mr. Zablotski, as always, your content does not disappoint, the quality of your videos is solid. Not a single video on your channel loses its consistency. Really useful and profitable. Every time I get the notification of a new video I am 95% sure that it will reach the high bars. God bless you man! PS2: Your videos are addictive, each one makes me want to watch another HAHAHAHA.

But even better - I absolutely love hearing that you're already putting what you learned into practice with your current project - that's fantastic, and that's what I wish people do - apply this knowledge directly! And thank you so much for the kind words about the channel! I try to deliver high-quality content, but never know whether it's good. Thus, your feedback means the world to me and keeps me motivated to keep creating!

    No problem. I had it too on my new computer, but then I installed one of the dependences (just another package) of the {performance} package and it worked. Forgot which exactly it is. So, just find out all the dependences of perfomance and sjPlot packages, install them and it will work. Please, write here in the comments for other folks which might have the same problem what package is was. Thanks forward.

    sure, it's not explicitely there, but if you run the code, it works. the package improves steadily and new functions are added all the time. another dependent and very cool package you can a look at is broom.helpers. they work together in parrallel, so if you did not installed it already, please do, and explore

    Thanks, Thiago! Your feedback is greatly appreciated! I already waited for somebody to say that the video might be overstimulating, so, you are the first who noticed. Congrats. I am still learning creating content. One of the principles is - show, don't tell. Therefore, I try to show everything, even text. Which, even for me is a bit too much. So, when you could point out which parts of the video, or which elements were distracting, and which parts were very good, I would be able to improve. Thanks!

    Mr Zablotski, I just found a video about the R packages "marginaleffects" and "modelsummary" on this college conference video kzread.info/dash/bejne/p62Cyq1qaK-yibg.html. Have you heard about them? What do you think about these packages and their features? Would you consider creating a package review video for them? No hard questions, just wanted to share this information and get more knowledge about it. Greetings from Colombia.

    Hey mate, thanks for the useful info! I did touch them once, but wasn't diving deep into it, because they were (despite being amazing tools!) not as quick and as intuitive as for example emmeans or gtsummary. But I'll have a look at the video and revisit the packages, and put them on the list, when I see some utility for data science. Thanks for watching by the way!
