SDA: a semi-parametric differential abundance analysis method for metabolomics and proteomics data.

abstract：BACKGROUND:Lung adenocarcinoma is the most common type of lung cancer, with high mortality worldwide. Its occurrence and development were thoroughly studied by high-throughput expression microarray, which produced abundant data on gene expression, DNA methylation, and miRNA quantification. However, the hub genes, which...
