In PelzKo/dwls: Dampened Weighted Least Square for Deconvolution of Bulk mRNA Data
Description
Usage
Arguments
Value
Examples
Description
Constrained ordinary least squares is implemented using a quadratic programming
approach, as such:
min_{x>0}||B-Sx||^2
S is a gene by cell-type signature matrix, B is a list containing bulk data, and x is
the number of cells from each cell type present in the bulk data. x is then
normalized:
\tilde{x} = \frac{x}{∑_{j=1}^n x},
where j is the cell-type index.
Usage
1
solveOLS(S, B)
Arguments
S
Gene by cell-type matrix consisting of averaged expression values across cells from each cell type
B
List containing bulk data values.
Value
List containing proportion of each cell type present in bulk data set.
Examples
1
prop <- solveOLS(S,B)
