Figure 1From: Bayesian hierarchical clustering for microarray time series data with replicates and outlier measurementsGamma prior on the total noise variance. A Gamma prior is assumed for the hyperparameter σ ε 2 . This reflects our prior knowledge that σ m 2 is a lower bound for the total noise variance. The total noise variance is unlikely to be greater than the total variance of the data, which is approximately unity because of normalisation, see Equation 7.Back to article page
