Accuracy and robustness of clustering algorithms for small-size applications in bioinformatics

Minicozzi, Pamela; Rapallo, Fabio; Scalas, Enrico; … - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 25, pp. 6310-6318

The performance (accuracy and robustness) of several clustering algorithms is studied for linearly dependent random variables in the presence of noise. It turns out that the error percentage quickly increases when the number of observations is less than the number of variables. This situation is...

Saturation and Quantization Reduction in Microarray Experiments using Two Scans at Different Sensitivities

Jorge GarcÃÂa de la Nava; Hijum, Sacha van; … - In: Statistical Applications in Genetics and Molecular Biology 3 (2007) 1, pp. 11-11

We present a mathematical model to extend the dynamic range of gene expression data measured by laser scanners. The strategy is based on the rather simple but novel idea of producing two images with different scanner sensitivities, obtaining two different sets of expression values: the first is...
