Likewise the recent research, we try to the learning method, the well-known classifier, such as SVM- RFE for large-scale gene expression profiling. Only diverse statistical methods including generalized linear model likelihood ratio test have validated the results of two significantly activate regulators in. RNA-seq data of 54 samples (normal colon, primary colorectal cancer (CRC), and liver metastasis) from 18 CRC patients are gener‐ ated in, which are identified significant genes associated with aggressiveness of CRC for identifying a prognostic signature with diverse progression and heterogeneity.

We have downloaded the colon dataset from NCBI- GEO, GEO Series accession number GSE2109 in Gene Expression Omnibus (GEO, ). Also we are interested in RNA-seq like colon, which was assayed using Illumina HiSeq 2000. Leukemia was assayed using Affymetrix Hgu6800 chips. This set was exploited with SVM-RFE based on MA-plot- based methods by R-package ‘DEGseq’. It was analyzed by using R-package ‘golubEsets’. To compare our implementation results with a well-known result of a microarray-based technology, we downloaded leukemia from their websites. This approach yields an alternative definition of the Riemann integral via a result of Darboux. In Section 6.4, we show that the Riemann integral of a function can be approximated by certain sums involving its values at more or less randomly chosen points. The Fundamental Theorem of Calculus and several of its consequences are proved in Section 6.3. Next, in Section 6.2, we establish a number of basic properties of integrable functions. Later in this section we prove a useful characterization of the integrability of functions, and also a key property of the Riemann integral known as domain additivity. In Section 6.1 below, we motivate and formulate a definition of Riemann integral. These connections manifest themselves mainly in the form of a central result known as the Fundamental Theorem of Calculus. Although this theory would seem unrelated to continuity and differentiability of functions, it has deep underlying connections. This leads us to the theory of integration propounded by Riemann. In this chapter, we embark upon a project that is of a very different kind as compared to our development of calculus and analysis so far, namely the project of finding the ‘area’ of a planar region of a certain kind.
