Origin has a built-in Principal Component Analysis tool which is used to explain the variance-covariance structure of a set of variables through linear combinations. And, we also provide an enhanced version of Principal Component Analysis tool, Principal Component Analysis app. This version offers ...
Sparse principal component analysis is a variant of PCA. While PCA find principal components which are linear combination of all input variables, Sparse PCA improved to select principal components whose linear combinations that contains only a few input variables. Thus the tool is useful in exploring...
Principal Component Analysis (PCA) is astatistical procedureand anUnsupervised Learning Algorithmforreducing the dimensionality of a data set while retaining as much information as possible. PCA does this by finding a set of new variables, called “Principal Components”, that arelinear combinations of...

“What is principal component analysis?” The post was motivated by a conversation I recently had with a well-known population geneticist at a conference I was attending. I mentioned to him that I would be saying something about PCA in my talk, and that he might find what I have to say...
