Top Scoring Pairs

Classification of patients into disease groups or subtypes is the most direct way to translate microarray technology into a clinically useful tool.Top scoring pairs (TSPs) are pairs of genes whose relative rankings can be used to accurately classify individuals into one of two classes. TSPs have two main advantages over many standard classifiers used in gene expression studies: (1) a TSP is based on only two genes, which leads to easily interpretable and inexpensive diagnostic tests and (2) TSP classifiers are based on gene rankings, so they are more robust to variation in technical factors or normalization than classifiers based on expression levels of individual genes.
