LAD variable selection for linear models with randomly censored data

Zhou, Zhangong; Jiang, Rong; Qian, Weimin - In: Metrika 76 (2013) 2, pp. 287-300

The least absolute deviations (LAD) variable selection for linear models with randomly censored data is studied through the Lasso. The proposed procedure can select significant variables in the parameters. With appropriate selection of the tuning parameters, we establish the consistency of this...

Effects of home-based Voluntary Counselling and Testing on HIV-related stigma: Findings from a cluster-randomized trial in Zambia

Jürgensen, Marte; Sandøy, Ingvild Fossgard; Michelo, … - In: Social Science & Medicine 81 (2013) C, pp. 18-25

HIV-related stigma continues to be a prominent barrier to testing, treatment and care. However, few studies have investigated changes in stigma over time and the factors contributing to these changes, and there is no evidence of the impact of HIV testing and counselling on stigma. This study was...
