From: mbDenoise: microbiome data denoising using zero-inflated probabilistic principal components analysis
Boxplots of error measures of estimation and prediction for mbDenoise and other methods. F1 and F2 denote the orthogonal projection distance and symmetric Procrustes error for predicting fi, B1 and B2 represent those for estimating βj, all averaged over 100 data replications, and time is the average computation time in seconds on the log base 10 scale. Absence of results for t-SNE in B1 and B2 was due to no estimation of βj in t-SNE
