solve_b: Solve for dataset specific shift b

In pengminshi/cFIT: cFIT (common Factor Space Integration & Transfer)

Description

argmin_{b_j>=0} ||X- HW^T diag(lambda_j) - 1_n b^T||_F^2

Usage

solve_b(X, W, H, lambd, b.gamma = 0.1)

Arguments

X	ncells-by-ngenes gene expression matrix
W	ngenes-by-r non-negative common factor matrix
H	ncells-by-r nonnegative factor loading matrix
lambd	numeric scalar, scaling associated with the dataset
b.gamma	tunning parameter for the L2 panelty on b.gamma.

Value

b shift vector of size p (ngenes).
