Experimental results on the H3N2 viral challenge dataset of gene expression profiles. (a) Estimated posterior distribution of the number of factors R. (b) Factor loadings ranked by decreasing dominance. (c) Heatmap of the factor scores of the inflammatory component clearly separates symptomatic subjects (bottom 9 rows) and the time course of their molecular inflammatory response. The five black colored pixels indicate samples that were not assayed.
