PCA is used to visualize these data by reducing the dimensionality of the data: The three original variables (genes) are reduced to a lower number of two new variables termed principal components (PCs). Left: Using PCA, we can identify the two-dimensional plane that optimally describes the highes… Principal component analysis (PCA) is a classic dimension reduction approach. It constructs linear combinations of gene expressions, called principal components (PCs). The PCs are orthogonal to each other, can effectively explain variation of gene expressions, and may have a much lower dimensionality.

PCA has the appealing feature of projecting individuals onto inferred axes of genetic variation that capture population structure in a continuous fashion. The standard way to infer population structure using PCA has been to construct a genetic relationship matrix (GRM) and perform eigendecomposition on this matrix to infer the axes of genetic
