On the other hand, if we want to analyze tectonic signals from PCA analysis, we still should remove unrelated or well-known signals from time series analysis. For example, if we want to extract post-seismic signals, the velocity, co-seismic jump, and seasonal terms should be removed. If ...

Principal Component Analysis Example:Continuing with the example from the previous step, we can either form a feature vector with both of the eigenvectors v1 and v2:Or discard the eigenvector v2, which is the one of lesser significance, and form a feature vector with v1 only:...
Keep in mind that principal components are not always interpretable. For this example, we’re fortunate we can interpret them to a degree. However, that’s not always possible. Principal component analysis prioritizes retaining information over creating interpretable components!

Principal component analysis is a versatile statistical method for reducing a cases-by-variables data table to its essential features, called principal components. Principal components are a few linear combinations of the original variables that maximall
