SparseM_solve {RItools} | R Documentation |
Helper function to slm_fit_csr
Description
This function performs some checks and takes action to ensure positive definiteness of matrices passed to SparseM functions.
Usage
SparseM_solve(x, y, ...)
Arguments
x |
A slm.fit.csr |
y |
A slm.fit.csr |
... |
A slm.fit.csr |
Value
list containing coefficients (vector or matrix), the Cholesky decomposition (of class matrix.csr.chol), and a vector specifying the indices of which values on the diagonal of x'x are nonzero. These are named "coef", "chol" and "gramian_reduction_index", respectively.
