Figure 1From: A hidden Markov model-based algorithm for identifying tumour subtype using array CGH dataA hidden Markov model for a cluster of tumor aCGH samples. There are n_g samples in cluster g, and the graph shows three DNA segment, t-1, t, and t+1. X is the unobserved copy number for each segment and y is the observed mean intensity value for each sample. Pg is transitional probability and Pgj is emission probability.Back to article page
