Statistics and informatics in molecular cancer research / edited by Carsten Wiuf, Claus L. Andersen.

Molecular understanding of cancer and cancer progression is at the forefront of many research programs. Complex mathematical, statistical and bioinformatics tools are required to extract, handle and process data and this book aims to make these tools available to a wide range of researchers, in a si...
