Table 1 Variance Explained By Principal Components. Table 1 lists the percentage of variance in the GNF human tissue microarray data explained by each principal component. The first 10 components explain 80.36% of the total variance. Principal components 11 through 158 each explain less than 0.5% of the total variance, but combined explain almost 20%.
