<p class="MsoNormal" style="text-indent:21.0pt;mso-char-indent-count:2.0"><span style="font-size: small;"><span style="font-family: Arial;"><span lang="EN-US">Single-dataset analysis of high-throughput omics data often leads to unsatisfactory results. The integrative analysis of heterogeneous raw data from multiple independent studies provides an effective way to increase sample size and improve marker selection results. In integrative analysis, the regression coefficient matrix has certain structures. In our study, we use group penalization for one- or two-dimensional marker selection and introduce contrast penalties to accommodate the subtle coefficient structures. Simulations show that the proposed methods have significantly improved marker selection properties. In the analysis of cancer genomic data, important markers missed by the existing methods are identified.</span></span></span><span lang="EN-US" style="font-family:"Times New Roman","serif""><o:p></o:p></span></p> |
