FAQ       Help    Most important PCA variables Question ID 130 Category Qlucore Omics Explorer   Analysis Date Created 2018-02-21 09:35:11 Date Updated 2018-02-21 09:47:47 Is there a standard way to identify which genes (variables) are important for each principal component in a PCA plot? Answer The importance of a given variable for a given PCA component is determined by the 'variable loadings' for that component. The higher the loading of a variable for the component, the more that variable contributes. The variable loadings can be exported together with the sample coordinates for an active PCA plot via File->Export->PCA Components.
