Modulus-Type Inner Outer Iteration Methods for Nonnegative Constrained Least Squares Problems
SIAM Journal on Matrix Analysis and Applications, 2016Summary: For the solution of large sparse nonnegative constrained linear least squares (NNLS) problems, a new iterative method is proposed which uses the CGLS method for the inner iterations and the modulus iterative method for the outer iterations to solve the linear complementarity problem resulting from the Karush-Kuhn-Tucker conditions of the NNLS ...

Correction Factor for Unbiased Estimation of Weibull Modulus by the Linear Least Squares Method
Metallurgical and Materials Transactions A, 2019In material science, linear least squares is the most popular method to estimate Weibull parameters for stress data. However, the estimation m^ of the Weibull modulus m is usually biased due to the data uncertainty and shorcoming of estimation methods. Many researchers have developed techniques to produce unbiased estimation of m.

where m and σ0 are the Weibull modulus and scale parameter, respectively. The most widely used method to estimate the two parameters from a set of experimentally measured fracture stresses is by using linear regression (LR), involving the ranking of the strength data in an ascending order and the assignment of probability of failure to each datum [2 ...
