This is one of the best explanations!!
ОтветитьThis is the best video for beginners to understand PCA. Thank you, Biostatsquid!
ОтветитьThank you for making it easy for me. God bless.
ОтветитьI think this is a very good explanation. The mathematics behind PCA is beautiful. However, this explanation is all you need. ❤
ОтветитьThis channel has been an invaluable resource for me. Thank you!
Ответитьbest and easy-to-understand explanation about PCA. Thanks a lot
ОтветитьThank you very much, its the best basic video about PCA 🎉❤❤
ОтветитьVery well explained
ОтветитьThis was a great video..can you do one for LDA and PLSDA....thank you❤❤
ОтветитьThanks for the great explanation of PCA 😊
ОтветитьThis was brilliant, thank you
ОтветитьI have a question:
Let's say I want to calculate the PCA of children's grades at school to know how it impacts the final grade average of each child. For that I have my sample, which would be all the children in a class, for example. Then I have the grades of those children in different subjects such as Math, History, Physical Education, etc. And I also have the average. Do I add the average as another variable to the PCA analysis? Or should I make a correlation, for example, between PC1 and the average and see the PCA loadings?
Very good teacher! Thanks!
Ответитьgood work. thanks
ОтветитьThanks for the video, this really explains it in a nutshell! This may be not in your alley, but what would PC2 to be if you would plot geochemical data with each variable being an element (PC1 seems to be rock type). Thanks in advance!
ОтветитьSUPERB THANKS <3
ОтветитьPerfect explanation for Principal Component Analysis
ОтветитьHow do someone find out the linear combination of PC1?
ОтветитьSo simple and clear. U are awesome.
ОтветитьThis is the best tutorial I have ever seen. Thank you so much.
ОтветитьGreat video. It explained PCA in a very simple and clear way. Thank you!
Ответитьi have suffered with PCA for two years and this video just made it so easy for me
Ответитьthe best video i found regarding loadings, but you don't mention the scores
ОтветитьBravissima
ОтветитьThanks!
ОтветитьWonderfully explained! Keep up the great work, Biostasquid.

ОтветитьIncredibly clear ! Thank you, and congratulation
ОтветитьAbsolutely brilliant explanation.
ОтветитьA big thank you!! I have this topic in my semester exams, and everyone around me is mugging up, upon asking what it is actually, they give me definitions that do not satisfy me, this single video clears a lot in understanding PCA. I wish I had a teacher like you in my college.
ОтветитьThank you for such informative, easy-to-understand content!
ОтветитьAlthough I don’t use PCA in my workday, I think this is the best video out there explaining how PCA works. Good job 👍
ОтветитьYou are exceptional 🤩
ОтветитьI have been struggling to understand PCA for days 🤯, despite reading many articles and watching countless videos, but this is by far the best and easiest to understand explanation, thank you!! 🥳
ОтветитьA very clear and engaging introduction to PCA. It was new to me, and I came away with a good impression of how it would be used. Thanks very much!😀
ОтветитьWhole world creator's godfather bless you all always and you all love and remember godfather with your pure hearts.
ОтветитьHow to explain which factors contribute to PC1 and PC2? by biplot graph.
ОтветитьI'm currently watching without logging into my Google account. 😊 However, halfway through, I made the decision to log in, hit the like button, and subscribe to your channel. 🎉 Thank you for your valuable content—it's truly helpful, and I encourage you to keep up the great work! 👍
ОтветитьHi thank you so much for explaining PCA in such a clear way. I've been really stressed about understanding it for my uni stats exam, but now I feel much more confident :)
ОтветитьVery good high level video!
ОтветитьPlease can u tell me how can we calculate principal loading. I am a bit confused to this part.
ОтветитьSo well explained. Thanks a bunch!
ОтветитьI have watched so many videos trying to understand pca ..and this by far is the most interesting with fundamentals fully explained
ОтветитьAmazing content, clearly explained! :)
Ответитьvery well explaining
ОтветитьSimply excellent !
ОтветитьI am now convinced that there are no tough subjects, only ineffective tutors. I have been struggling to understand this concept for over 3 years, and here I am, within 11 minutes things have fallen into place.
An expert not necessarily be a great teacher. There might be great experts assigned in educational institute to teach such concepts.
But someone like you is what we need in our schools and colleges (expert and well articulated).
Simplicity is the utmost form of sophistication.
Thanking you from the bottom of my heart.
Keep on helping people like us.
Perhaps another video on how to do it in R will be great hit.
it's well explained for begginer to understand the plot,but if you wanna know how to do it,this video can't help you
