Figure 1From: Probabilistic estimation of microarray data reliability and underlying gene expressionSchematic diagram illustrating the transition from underlying to observed distributions of states, in the case of m = 4 samples. The underlying distribution on the left hand side can be described by the probabilities for each underlying state, P(σ1), P(σ0), and P(σr) (see text). This distribution is then distorted by sample specific errors, and , resulting in an experimentally observed distribution, depicted on the right hand side.Back to article page
