Karl Pearson is credited with the development of PCA in 1901, but it gained popularity with the increased availability of computers, which allowed for multivariate statistical computations1at scale. PCA is very effective for visualizing and exploring high-dimensional datasets, or data with many feature...
Stepwise Regression and PCAHi wishes all of u well. i am working on a project where 7 input and 1 output. The data is in numerical form. i want to apply stepwise Regression and PCA. any one please give me example code that help me in this regards. i use stepwise(x,y) function but...
. I will not delve into the details of SVA in this post, except to say that the overall idea is to first perform linear regression (assuming no hidden factors) to identify the parameters and to then perform singular value decomposition (SVD) on the residuals to identify hidden factors (deta...
