Very useful and helpful explanation. Thanks warmly :-)
Thank you for this video! The visualizations are really helpful!
One question: I was just wondering, when using the pca() function, if the matrix X needs to be centered at origin and be standarized. This confused me a bit...Thank you in advance :)
What if i want insted of principal component 1 and 2, get the plot of principal variables .
if i have the times series data for subjects over a number of brain regions, what should i take variables as?
I have data with voltage,current and power according to its duration. How do i do PCA on it?
