Estimating effects of rare haplotypes on failure time using a penalized Cox proportional hazards regression model

BMC Genetics, 2008
Background This paper describes a likelihood approach to model the relation between failure time and haplotypes in studies with unrelated individuals where haplotype phase is unknown, while dealing with the problem of unstable estimates due to rare ...

A working set SQCQP algorithm with simple nonmonotone penalty parameters

Journal of Computational and Applied Mathematics, 2011
The authors consider the inequality constrained nonlinear programming problem \[ \min_{x\in\mathbb{R}^n}\,f(x)\quad\text{s.t. }g_j(x)\leq 0,\;j\in I=\{1,2,\dots,m\} \] and present a new sequential quadratically constrained quadratic programming (SQCQP) algorithm, in which a simple updating strategy of the penalty parameter is adopted.

A stabilized algorithm for multi-dimensional numerical differentiation

Journal of Algorithms & Computational Technology, 2016
We develop a multi-dimensional numerical differentiation method in this paper. To obtain stable numerical derivatives, the Tikhonov regularization method in Hilbert scales is proposed to deal with illposedness of the problem. The penalty term in Tikhonov

A penalty approach for a box constrained variational inequality problem [PDF]

, 2018
summary:We propose a penalty approach for a box constrained variational inequality problem $(\rm BVIP)$. This problem is replaced by a sequence of nonlinear equations containing a penalty term. We show that if the penalty parameter tends to infinity, the
