[玫瑰]看到今天的小文，想起昨天在我们6q老师的亲子讲座中，家长问到三个问题，分别是：拖拉；孩子说话慢；孩子总是犯.. Introduction. Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components ( Wikipedia). PCA is a useful tool for exploring patterns in highly-dimensional data (data with lots of variables) [R-br] Instalar pacote do github. Caros, Certa vez eu consegui instalar o pacote ggbiplot que considero bem interessante. Não sei se pela atualização do R, ou de mudança de versão do Windows,.. ggbiplot. In an answer to a question posted on CrossValidated, I provided an example of a biplot using the R package ggplot2.I've gotten several inquiries about it, so I've decided to bundle it into an R package and to make it available on github: ggbiplot. To install the package The following relies on the Iris dataset in R, and specifically the first three variables (columns): Sepal.Length, Sepal.Width, Petal.Length.. A biplot combines a loading plot (unstandardized eigenvectors) - in concrete, the first two loadings, and a score plot (rotated and dilated data points plotted with respect to principal components). Utilizing the same dataset, @amoeba describes 9.

PCA and factor analysis in R are both multivariate analysis techniques. They both work by reducing the number of variables while maximizing the proportion of variance covered. The prime difference between the two methods is the new variables derived.
