Fig. 3From: Cross-study analyses of microbial abundance using generalized common factor methodsSimulation results for decreasing eigenvalues and five common eigenvectors, with sequencing depth correction; p=50, \(n_1=200\), \(n_2 = 100\). “None” as a common basis label means that Group 1 and Group 2 data were concatenated prior to variance estimation. The true common variances are in solid black; the true unique variances are in black outline-onlyBack to article page
