Similarity of Multivariate Methods to Establish Microarray Quality Control Standards
Summary: This article describes a multivariate method based on logistic regression that distinguishes between usable and low-quality digital image spots associated with DNA microarray data analysis. To create a response variable describing spot quality, the authors analyzed the similarity among decisions that were made with control charts applied to quality parameters established in the gene expression measurement literature.
