| Abstract: | With a class of high-dimensional & small-sample data,Prediction models of small-sample are constructed using Hypothesis Test and Partial Least-Squares Regression(PLS) of statistical methods,which carried out variables selection on wilcoxon rank-sum test and variables compression & dimension reduction on PLS.And small-sample modeling and visualization on statistical methods are achieved by the instance of DNA sequence classification,the results show that the modeling methods of small-samples have feasibility and stability. |
| Keywords: | small-sample wilcoxon rank-sum test partial least-squares regression dna sequence classification |
