In xuranw/wdec: Multi-subject single cell deconvolution

Estimate cell type proportion with MuSiC and NNLS

Description

Estimate cell type proportion with MuSiC and NNLS

Usage

music.basic(Y, X, S, Sigma, iter.max, nu, eps)

Arguments

Y	vector of bulk tissue expression
X	matrix, Signature matrix
S	vector of Avg. Library size
Sigma	matrix of Subject level variation (gene * cell type)
iter.max	numeric, maximum iteration number
nu	regulation parameter, take care of weight when taking reciprocal
eps	Threshold of convergence

Value

a list with elements:

• p.nnls: vector of cell type proportions estimated by nnls (add up to 1);

• q.nnls: vector of original estimation from nnls;

• fit.nnls: fitted value of Y from nnls;

• resid.nnls: residual value from nnls;

• p.weight: vector of cell type proportions estimated by weighted-nnls (add up to 1);

• q.weight: vector of original estimation from weight-nnls;

• fit.weight: fitted value of Y from weighted-nnls;

• resid.weight: residual value from weighted-nnls;

• weight.gene: weight calculated from weighted-nnls;

• converge: 'Reach Maxiter', 'Converge at m';

• rsd: residual value from weighted-nnls transformed by weight;

• R.squared: R square of weighted-nnls;

• var.p: variance of weighted-nnls estimated cell type proportions;
