Figure 3From: Missing value imputation for microarray data: a comprehensive comparison study and a web toolPerformance comparison of different methods on SP_ALPHA. In the SP_ALPHA, the performances of all algorithms were estimated by three indices (NRMSE, CPP and BLCI). Each point represents the average rank for each algorithm. Different colors (blue, red and green) represent the results evaluated by different indices. The error bar is the standard error.Back to article page
