CAMASObj-class: Class "CAMASObj"

In Lululuella/CAMTHC: Convex Analysis of Mixtures for Tissue Heterogeneity Characterization

Description

An S4 class for storing estimated proportions, subpopulation-specific expressions and mdl values. The mdl values are calculated in three approaches: (1) based on data and A matrix in dimension-reduced space; (2) based on original data with A matrix estimated by transforming dimension-reduced A matrix back to original space; (3) based on original data with A directly estimated in original space. A and S matrix in original space estimated from the latter two approaches are returned. mdl is the sum of two terms: code length of data under the model and code length of model. Both mdl value and the first term (code length of data) will be returned.

Slots

Aest

Estimated proportion matrix from Approach 2.

Sest

Estimated subpopulation-specific expression matrix from Approach 2.

Aest.proj

Estimated proportion matrix from Approach 2, before removing scale ambiguity.

Ascale

The estimated scales to remove scale ambiguity of each column vector in Aest. Sum-to-one constraint on each row of Aest is used for scale estimation.

AestO

Estimated proportion matrix from Approach 3.

SestO

Estimated subpopulation-specific expression matrix from Approach 3.

AestO.proj

Estimated proportion matrix from Approach 3, before removing scale ambiguity.

AscaleO

The estimated scales to remove scale ambiguity of each column vector in AestO. Sum-to-one constraint on each row of AestO is used for scale estimation.

datalength

Three values for code length of data. The first is calculated based on dimension-reduced data. The second and third are based on the original data.

mdl

Three mdl values. The first is calculated based on dimension-reduced data. The second and third are based on the original data.
