Prior knowledge of programming and statistics is not required. We shall lay a good foundation in the basic quantitative analysis & upgrade into more advanced statistical analysis (statistical tests, different classes of regression models: fixed & mixed-effect regression models, machine learning algorithms, advanced data visualization, data cleaning in R, etc.). We will also learn adequately about looping (for loops, while loops, etc.), use of apply functions (lapply, sapply, mcapply, etc.), storing results from loops as a vector, matrix or three-dimensional array; writing your own functions for some tasks to prove some theorems (central limit theorem, bootstrapping, jackknife and hypercube sampling schemes, etc.), doing novel simulations (of probability distributions, and other statistical processes) and parallelising codes for high speed depending on the complexity of the problem, use of existing libraries/packages for data analysis, amongst others. Lots of practice tasks assigned.

Kindly how we get your presentations. Thanks dr
Can I get your email sir
Hello sir I need assistant on regression for a company 4 years financial statement.
There is no sound.
Kindly check if your TH-cam isn't muted. It must be from your end, please. Kindly check at your end, because it is working perfectly.
@@clementtwumasieducativecha674 Ok thx.
Very grateful to see you in this again. Indeed, you have inspired me to become an R lover. I now code like an expert. thanks to you Dr. Stocha....
Great to see again Dr, i chance your videos on R when pursuing your PhD, it really helped me. thank you
Very humbled to hear this. Cheers👍
Beautiful presentation
Very humbled to hear this👍
This is hard...keep it up bro

Please, how can get all the resources. Do you have a gihub account where all your codes are available so that i could play with it, for my studies. Thank you so much, your videos are very impactful.
I use a platform called Piazza to manage the materials I use for my TH-cam videos. You can email me at clement.twumasi@ndm.ox.ac.uk, requesting to sign up for my Piazza platform. Once you sign up, you can access all the R codes and data for my TH-cam videos at no cost. Cheers.

Well than big bro. I'm happy to see what you are doing. I'm also a Ghanaian.🎉
Love from Pakistan 🇵🇰

great video.
Beautiful
I have really enjoyed the lecture
My knowledgeable bro
Cheers my brother
hello Clement, can you please have a video on DCE and BWS designs in R software and also can you pls help me with a free software that can help me get the choice exercise for choice experimental studies?
I will look into that. Cheers
What will be the consequences of not changing the alpha value from 0.05 to 0.025 even when you are doing a two-tailed anaysis?
I will demonstrate that in my new video.
Let me just answer you here. In summary, not changing the alpha value from 0.05 to 0.025 in a two-tailed analysis can lead to an increased risk of Type I errors, less stringent criteria for significance, potential misinterpretation of results, and a compromise in the validity of the research findings. Adjusting alpha levels appropriately is crucial to ensure the reliability and accuracy of statistical hypothesis testing.
Yh, the video was insightful and will be expecting it to be re-uploaded soon. If you can touch on calculating the effect size in the software (G*Power), that will be great. Clicking on the "Determine =>" tab opens up a new tab which allows you to input parameters to calculate the effect size
Yh, I will certainly do that. Your previous comment was beneficial. Thanks for that.
Thanks for helping us
May God continue to broaden your horizons Dr. Clement. Continue the good work
It's wonderful
Really appreciate your content
Congratulations Dr.
Beautiful song by all standards
congrats
Go Ahead
great one
Hi Dr. Clement, please I have been following your videos for a while... However, I don't have access to your the written contents (pdf, docx etc) on Piazza because I am in Nigeria... Please, what assistance can you render for me sir?
Please send me an email via c.twumasi@imperial.ac.uk requesting to be added to my Piazza platform. Follow-up emails will be sent.
can this be helpful, I just registered for a course applied regression analysis ?
You can go through the videos and you will learn more on regression analysis (including more advanced types)
God bless you so much for availing yourself for u
Humbled, my brother 😊🙏🏿
Thank you for your sharing of information about mendeley. I need to know how to use mendeley in APA 6th citation style with chronological order of many authors in text citations
Thank you Dr.
Thanks. Well loaded info within a limited time. R markdown does the same thing as the Jupyter notebook.
Well done Clement🥰🙏🏾😘
Great work you are doing here Clement. I am not a fan of Jupiter notebooks though. The entry of Quarto makes Jupyter my last option.
Hello, If I may suggest; please use R-markdown and perhaps dispaly the entire screen so the code is visible. The first lesson gave me difficulties with the else statement.
When one starts an R class, it's imperative to introduce R studio as an IDE before moving on to more advanced IDEs. You will notice in subsequent videos that Jupyter notebook was used as the IDE for teaching.
@@clementtwumasieducativecha674 ok, understandable. Thank you
Knowledge is power and R has the Statistical power. Thank you for sharing Dr.Clement
Certainly 😊

Thank you Dr.
Thanks brother I have a question, I did not had a good experience with QuillBot in terms of paraphrasing, as it changes too much some time weird sentences. My questions are why you chose Quillbot for paraphrasing? Are there other tools? And what exactly you looked for when u come across this tool? and plz provide a feedback what else a paraphrasing tool should have in terms of functional requirements? thanks in advance for reading out my long comment but plz reply :)
Usually, when you use any software or application, read through its outputs/outcomes before usage. There may be other paraphrasing software (which you can google to find out), but Quillbot has been observed as a good alternative coupled with Grammarly. Once you paraphrase, read the output and make sure some key words are not excluded.
