Investigators have two important questions to consider when evaluating microarray expression data. First, they must ask whether the results are valid—in other words, accurate—for the particular ...

Microarray technologies are generating new data at a breathtaking speed. Because of the sheer size of these data and the technical complexity involved in microarray chip designs, it is a challenge to ...

For biologists, DNA microarrays present at once unprecedented opportunities and monumental challenges. In the opportunities column, microarrays produce genome-wide gene expression snapshots, ...

To combat that problem, Lin helped found an annual competition called Critical Assessment of Microarray Data Analysis (CAMDA; www.camda.duke.edu). The idea is to present statisticians with published ...
