WebJun 14, 2024 · If 2 clusters of mice are different based on PC1, like the blue and orange clusters in this plot, such differences are likely to be due to the genes that have heavy influences on PC1. If 2 clusters are different based on PC2, like the red and blue clusters, then the genes that heavily influence PC2 are likely to be responsible.
WebTo statistically determine what groupings, or clusters, of samples in PC1-PC2 space were related, a model-based hierarchical cluster analysis was run using the function Mclust (Fraley et... WebAug 8, 2024 · So, transforming the data to comparable scales can prevent this problem. Mathematically, this can be done by subtracting the mean and dividing by the standard deviation for each value of each variable. Once the standardization is done, all the variables will be transformed to the same scale. Step 2: Covariance Matrix computation
