Traditionally, the statistical method for obtaining the miRNA targets from the microarray expression data is based on correlation analysis. However, the experimental results reveal that the correlation analysis cannot lead to very accurate results resulting in a large false discovery rate. Therefore, Wang and Li (2009) establish a relative squared method based on a regression model to find miRNA interactions from microarray data, which is shown to outperform the correlation analysis and another existing method. Although RRSM is successful in selecting high-confidence miRNA targets from the microarray data, its theoretical properties have not been deeply explored. In this study, we will investigate and derive the theoretical properties for RRSM. 官方說明文件#: NSC101-2118-M009-006-MY2 URI: http://hdl.handle.net/11536/98801https://www.grb.gov.tw/search/planDetail?id=2590243&docId=391312 顯示於類別： 研究計畫
