WebApr 8, 2024 · When we multiply the original centered data with the eigenvectors we get the new matrix DE which contains the transformed data, our principal components, and our principal component scores. The new matrix DE contains our principal components, where each column is a principal component. WebPART 1: In your case, the value -0.56 for Feature E is the score of this feature on the PC1. This value tells us 'how much' the feature influences the PC (in our case the PC1). So the higher the value in absolute value, the …

WebDec 14, 2024 · Since we are performing principal components on a correlation matrix, the sum of the scaled variances for the five variables is equal to 5. The first principal component accounts for 57% of the total variance (2.856/5.00 = 0.5713), while the second accounts for 16% (0.809/5.00 = 0.1618) of the total. http://www.sthda.com/english/articles/31-principal-component-methods-in-r-practical-guide/112-pca-principal-component-analysis-essentials cheers farm appleton
