  "Description": "Tensor Composition Analysis (TCA) allows the deconvolution\nof two-dimensional data (features by observations) coming from\na mixture of heterogeneous sources into a three-dimensional\nmatrix of signals (features by observations by sources). The\nTCA framework further allows to test the features in the data\nfor different statistical relations with an outcome of interest\nwhile modeling source-specific effects; particularly, it allows\nto look for statistical relations between source-specific\nsignals and an outcome. For example, TCA can deconvolve bulk\ntissue-level DNA methylation data (methylation sites by\nindividuals) into a three-dimensional tensor of\ncell-type-specific methylation levels for each individual (i.e.\nmethylation sites by individuals by cell types) and it allows\nto detect cell-type-specific statistical relations\n(associations) with phenotypes.
