From: Adaptive filtering of microarray gene expression data based on Gaussian mixture decomposition
Comparison of methods for discovery of DEGs based on ALV and AV filtering to PVAC filtering algorithm. ROC curves for different filtering methods for spike-in dataset. Different colors correspond to different filtering types of filters: red color is assigned to the filtration in sample variance domain, blue - sample mean, green - sample variance in log scale, purple - PVAC method, and black - no filtration. Different line styles correspond to different methods: solid line shows the results for adaptive filtering, dashed and dashdot line - fixed threshold filtering. Percentage of the removed genes after PVAC filtering is 76.2.
