Multiple regression. How to deal with Outliers and Colliniarity
Переглядів 2,8 тис.3 місяці тому
When doing linear regression or multiple regression, your data may have outliers. Outliers are data points where the residual values are far from the model. In this video we explore how to identify outliers and discuss what to do when they are found. Colliniarity or multicolliniarity occurs when two or more of the explanatory variables are correlated. There are times when these variables should...
Simple Linear Regression.
Переглядів 4 тис.4 місяці тому
This is the fist in a series of videos that focus on Multiple Regression. Our starting point is to understand simple regression before building upon that understanding. Regression analysis considers the relationship between an explanatory variable and an outcome variable and allows us to understand how much of the outcome variable can be explained by the explanatory (or independent) variables. ...

Doing a t-test using R programming (in 4 minutes)
Nice presentation. Although I am not a big fan of plotly which I find cumbersome and convoluted compared to ggplot2. Neither am I a fan of 3D plots in general. I find them to be misleading and better to use 2D with other type of coding (color, size etc) or faceting for the 3rd dimension. Thanks.
Fair enough! good points... :)
nimic n am inteles sa mi bag pl
I used plotly to visualise results from a latent profile analysis on personality scales (similar to your interactive eye colour visual) - wondering now what else I could do with plotly on those results ... ? Thanks for this, love your tutorials!
Looking forward to seeing what else you might do!! Thanks for the feedback.
Thanks a lot Greg. I love your videos and reels. Can you exlpain bit about Logistic regression?
Sure thing! - Will make some videos about that soon
Marvelous as usual 🎉. Awesome. Thank you
Thanks for the feedback :)
I have zero knowledge on programming, so it is not easy-pizzy for me. What to start with? I need only to create damp plots that is it
Watch his past videos; they build a solid foundation for these current tutorials. I assure you, he is one of the best, if not the best, R tutors out there.
Thanks for that comment @NattyGism... Yes, @maximzhentichka360 - please do go to my channel and start at the beginning. Hopefully you'll get the help you need. www.youtube.com/@rprogramming101
It's great 💯👍
Yes - I agree, plotly is great
I watched it first 🎉 awesome video thank you!
Yay! Thank you!
the "bumshakalaka" caught me off guard hahhahahhahahhahahhahahhah Great video
thanks :)
Introduction to Periodic chemistry
Thank you so much for these amazing tutorials!🙏I have recently found your channel and they are EXTREMELY helpful. They are helping me a lot in my data analysis in my PhD. If possible, could you kindly make a tutorial video on how to use RSA R package to do polynomial regression and response surface analysis to test congruence/incongruence (Edwards 2002). Thank you and please keep making these amazing tutorials!🙏🙂
Hi Greg, I am new to R and the whole world of programming. I found your first video very educative, but where do I go from here? I thought you had a numbered series of videos that would teach how me the complete language. I visited your page, and there are so many videos, I literally don't know which one to use. it is possible to do a series of videos from beginner to advanced use of R. thank you.
Very helpful! Thank you, sir!:D
Glad it was helpful!
Cool trucks. Explained in 5 mins! Great job, thanks.
Glad it was helpful!
Hello, could anyone help me? I've been trying this code, and instead of showing the animated plot in the Viewer pan, I get 100 png files saved in my working directory Would you know how to fix it?
I learned so much from your videos... Thank you for new lrearnings!...
Happy to hear that!
Wow this is lovely. I will use this today. Thanks Greg!
Such a wonderful way to introduce new concept and making it super easy to understand! Thanks much, Greg!😎
thanks
I had to say I did fall in love with r as I am getting in data analysis and it made me feel at ease
glad you love it!! :)
Thank you so much, you have made R easy to understand
You're very welcome!
Cada tanto R programming nos recuerda el inmenso potencial y uso de R, Gracias.
Thx , great tutorial. All great except the ugly arrows ;) The semi curved ones are much more aestheically pleasing imho.
haha - will work on that :)
drop_na(column_name) is given as error. What should I do?
You just make me keep falling for R. Thanks Greg
haha - you are welcome
So cool!
thanks
Boom Shaka lala Nice one!
haha
Very nice! gganimate is sort of like a flip-book. Flip the pages and get movement. I would like to see this done with maps.
Ooooh nice idea - animation with maps (I hadn't thought of that!). Let's do it!!
nice chanel, thank you
Thanks and welcome - glad you like it.. :)
Very well done. Thanks for
Thank you too!
Very cool and super straight-forward. Have you played around with plotly in R?
hi @pipertripp - yes, I LOVE plotly and have a video almost ready to go on that. Absolutely lovely stuff. Glad you enjoyed this one.
This is great....
glad you like it.. more to come... :)
I am the first to see this video ... yeah 😅
haha - well thanks for watching!! :)
Hi, I was wondering if you teach R in online live lessons? I am a beginner and was wondering if this is something you offer.
hi there - I don't (but might do so in the future). I do have online courses though that you can look at at www.learnmore365.com
random clicking and dropping sounds.
will look into that.
Thank you so much Dr Martin for your help. I am glad that the best person teaching R on this website is a fellow South African. I do have a tiny pet peeve that I want to express regarding the sound design. I feel like the sound effects can sometimes be a bit jarring and take you out of the learning experience. I am unsure who edits your videos, but I would suggest that they mix your vocals up or the sound effects down, to produce a better experience. Sorry for the complaint, but a massive thank you from Stellenbosch!
Hi there - thanks for the feedback!! Well received. I'll look into the sound thing. Always good to get feedback so I'm really appreciative. Hope you are enjoying lovely Stellenbosch!! Keep in touch. Greg
Healthy dose of R . Got here looking for Quarto tutorials.
haha - well I do love Quarto - that's for sure.. I have a video about it. Hope you enjoy the channel.
i need the files or data sets
Excellent simplified explanation. Not everyone is gifted to teach but truly you are.
that's very kind of you to say - thanks.
I always create a folder for each project and then create a new txt and finally change .txt to .R
Ah - interesting - i like it.
Excellent!!
thanks
How do you get the friends.csv?
Question, I wasn't able to install Starwars in my R Studio. It said it wasn't available on my version of R. I have a MacBook Pro with a mac OS version of R. Does anyone have any solutions?
Nevermind. I was able to get it downloaded on my own so I can now follow along with this video
Glad its sorted - happy day.
You're amazing at teaching this. Thank you!
you are most welcome melina.
Everything worked up to plot(). I get "Error in plot.default() : argument "x" is missing, with no default"
oooh - I'll look into that.
Thanks for this. Has the plot function completely changed since this video? I am getting an error message.
thanks for letting me know.
Great video
Glad you liked it - thanks for the feedback
Really great
glad you liked it
❤
Good videos and instructions, but I can't try anything without the data.
hi there - type data() into r studio and you'll see a list of datasets built in that you can practice with.
Thank you!🥺
you are most welcome.
