Isochores Merit the Prefix 'Iso'
Wentian Li, Pedro Bernaola-Galvan, Pedro Carpena +1
The isochore concept in human genome sequence was challenged in an analysis by the International Human Genome Sequencing Consortium (IHGSC). We argue here that a statement in IGHSC…
Simplifying the mosaic description of DNA sequences
Rajeev K. Azad, J. Subba Rao, Wentian Li +1
By using the Jensen-Shannon divergence, genomic DNA can be divided into compositionally distinct domains through a standard recursive segmentation procedure. Each domain, while sig…
How Many Genes Are Needed for a Discriminant Microarray Data Analysis ?
Wentian Li, Yaning Yang
The analysis of the leukemia data from Whitehead/MIT group is a discriminant analysis (also called a supervised learning). Among thousands of genes whose expression levels are meas…
Zipf's Law in Importance of Genes for Cancer Classification Using Microarray Data
Wentian Li
Microarray data consists of mRNA expression levels of thousands of genes under certain conditions. A difference in the expression level of a gene at two different conditions/phenot…
DNA Segmentation as A Model Selection Process
Wentian Li
Previous divide-and-conquer segmentation analyses of DNA sequences do not provide a satisfactory stopping criterion for the recursion. This paper proposes that segmentation be cons…
New stopping criteria for segmenting DNA sequences
Wentian Li
We propose a solution on the stopping criterion in segmenting inhomogeneous DNA sequences with complex statistical patterns. This new stopping criterion is based on Bayesian Inform…
