TLDR
We prove that a single condition, which we call the Irrepresentable Condition, is almost necessary and sufficient for Lasso to select the true model both in the classical fixed p setting and in the large p setting. Expand

  • 6 September 2006
TLDR
We investigate the general residual life (GRL) of a (n-k+1)-out-of-n system with i.d. components, given that the total number of the failures of components is less than l-1(1lesl<klesn) at time tges0. Expand

Evaluation of commercial building HVAC systems as frequency regulation providers
Abstract The heating, ventilating and air-conditioning (HVAC) systems of large commercial office buildings consume a significant amount of electric power. Instead of passively consuming energy, theseExpand
