Principal component analysis (PCA) is a technique to simplify the analysis data, and also is a visualization method for studying the similarity or difference of data. This method can effectively find out the most important elements and structures in the data and remove noise and redundancy. It also can reduce the dimension of the original complex data and reveal the simple structure hidden behind the complex data.
By analyzing the composition of OTU (97% similarity) of different samples, the differences and distances between samples can be reflected. PCA uses variance decomposition to reflect the differences of multiple sets of data on the two-dimensional coordinate graph. The coordinate axis takes two eigenvalues that can reflect the variance value to the maximum. For example, the more similar the sample composition, the closer the distance reflected in the PCA plot. Samples in different environments may show dispersion and aggregation. The two or three components with the highest interpretation degree of sample difference in PCA results can be used to verify hypothesis factors.
