The Performance of Group Lasso for Linear Regression of Grouped Variables

The lasso [19] and group lasso [23] are popular algorithms in the signal processing and statistics communities. In signal processing, these algorithms allow for efficient sparse approximations of arbitrary signals in overcomplete dictionaries. In statistics, they facilitate efficient variable selection and reliable regression under the linear model assumption. In both cases, there is now ample ...

Finite sample e ciency of OLS in linear regressionmodels with long - memory disturbances 1

OLS is as e cient as GLS in the linear regression model with long-memory errors as the long-memory parameter approaches the boundary of the stationarity region, provided the model contains a constant term. This generalizes previous results of Samarov & Taqqu (Journal of Time Series Analysis 9, 1988, pp. 191200) to the regression case and gives a further example of the `high-correlation asymptot...

Comparing The ANN And Linear Regression In Estimation Of The Growth Model (The Case Of MENA)

Seminal plasma HIV-1 RNA concentration is strongly associated with altered levels of seminal plasma interferon-γ, interleukin-17, and interleukin-5.

Seminal plasma HIV-1 RNA level is an important determinant of the risk of HIV-1 sexual transmission. We investigated potential associations between seminal plasma cytokine levels and viral concentration in the seminal plasma of HIV-1-infected men. This was a prospective, observational study of paired blood and semen samples from 18 HIV-1 chronically infected men off antiretroviral therapy. HIV-...
