Bayesian system identification of molecular cascades

Abstract

We present a Bayesian method for the system identification of molecular cascades in biological systems. The contribution of this study is to provide a theoretical framework for unifying three issues: 1) estimating the most likely parameters; 2) evaluating and visualizing the confidence of the estimated parameters; and 3) selecting the most likely structure of the molecular cascades from two or more alternatives. The usefulness of our method is demonstrated in several benchmark tests. © 2008 Springer-Verlag Berlin Heidelberg.
