Thank you for the clear summary! I just have one small question about your blog the barplot for the function "plot_xtab" had frames, I can't find an argument on the package guide for that? am I missing something?

@yuzaR-Data-Science

6 ай бұрын

the design of plots can be changed with themes from ggplot. so, no argument inside of plot_xtab is needed. Here is an example: plot_xtab( x = Wage$education, grp = Wage$jobclass, margin = "row", bar.pos = "stack", show.summary = TRUE, coord.flip = TRUE) + theme_blank() try our other theme too, like theme_bw() etc. Thanks for positive feedback! :)

Sir is it possible to merge frequency and percentage in single column in cross tab table in sjPlot like n(%) as in gtsummary package

@yuzaR-Data-Science

Жыл бұрын

you could force it using dplyr, but I would just decide which one, gtsummary of sjPlot I want and take that one. Both are great!

I understand that for the estimates plot (default plot_model), the bar means the 95% confidence interval. But for the predictions ( plot_model(type = "pred") ), what does the bar mean? Is the dot the average prediction for that category, and the bar the standard deviation? Also, if a model includes several predictors (y = a + b + c), showing the prediction plot of one of them (a) corrects for the effects of the others, right? Amazing video, made with a very good explanation and a lot of work on the visuals too!

@yuzaR-Data-Science

Жыл бұрын

Both bars show 95% CIs by default. You can learn more by asking R about it: "?plot_model". And yes, the model "corrects" for other predictors, or, as I like to think about it, it calculates what we want when other predictors are stable (usually at average). Thanks a lot for a feedback and thanks for watching! Cheers

Ahoy Yury (lovin' all you videos lately), at 6:28 you mention a "random effects of education" term. Can you explain what this is a bit more?

@yuzaR-Data-Science

2 ай бұрын

Thanks Julian! Don't worry about random effect in this particular example, it was meant to clarify the effect of wage end jobclass on age ... (because random effects takes out some unwanted variance in the data), but I guess it only produced more questions. Again, forget about it in this example. But I plan to cover mixed effects models in the future. However, if you wanna dive into it earlier, I can recommend a very good book for it "Mixed Effects Models and Extensions in Ecology with R". cheers

@@yuzaR-Data-Science Thanks Yury... one questions that's popped up for me, in binge-ing through your videos is "what happens when the data doesn't meet the assumptions required for linear regression?" Like, I know that sometimes there can be some transformations used to get certain variables better situated for this type of modelling... and other instances where alternative modelling types have to be used (I'd be interested in what the differences would be between runnign the original linear regression -even though the data fails the assumptions -vs the results of running the alternative model(s). Anyway, totally no pressure, just an idea for a future video 🙂

Hey Julian, that's a great idea, I actually did such comparison in several videos already. For instance, robust and quantile regressions (even 2 videos there). So, feel free to check them out. But there is no general rule what to do, because even when you log-transform data, it does not always solve the non-normality or heteroskedasticity. But yeah, QR often helps.

The factet barplots are crowded. Although that is fixed in an expanded plot in a script file it does not scale in an RMarkdown or Quarto file.
