get_cox_qr_solve {catalytic} | R Documentation |
Solve Linear System using QR Decomposition
Description
This function solves the linear system defined by hessian_matrix
and gradient_vector
using QR decomposition. Any NA values in the resulting solution vector are replaced with 0.0001. If there
is an error during the solution process, a vector of default values (0.0001) is returned instead.
Usage
get_cox_qr_solve(hessian_matrix, gradient_vector)
Arguments
hessian_matrix |
A matrix of coefficients representing the system of linear equations. |
gradient_vector |
A numeric vector representing the constants in the linear system. |
Value
A numeric vector representing the solution to the linear system. NA values in the solution are replaced with a small value (0.0001). If an error occurs during solving, a vector of default values (0.0001) is returned.
