We present a Bayesian model for two-way ANOVA-type analysis of high-dimensional, small sample-size datasets with highly correlated
groups of variables. Modern cellular measurement methods are a main application area; typically the task is differential analysis
between diseased and healthy samples, complicated by additional covariates requiring a multi-way analysis. The main complication
is the combination of high dimensionality and low sample size, which renders classical multivariate techniques useless. We
introduce a hierarchical model which does dimensionality reduction by assuming that the input variables come in similarly-behaving
groups, and performs an ANOVA-type decomposition for the set of reduced-dimensional latent variables. We apply the methods
to study lipidomic profiles of a recent large-cohort human diabetes study.
