Infinite sequences with sign-symmetric Liouville distributions
Infinite sequences sign-symmetric Liouville distributions
2009/9/22
We define and study the sign-symmetric Dirichlet-type
and Liouville-type distributions on n-dimensional space. We give
a complete stochastic representation for infinite sequences of random
variable...
A characterization of sign-symmetric Liouville-type distributions
A characterization sign-symmetric Liouville-type distributions
2009/9/22
Sign-symmetric Liouvillstype distributions on n-dimensional
space are characterized by certain (n- 1)-dimensional distribution
of quotients in a special form.
Sup-norm convergence rate and sign concentration property of Lasso and Dantzig estimators
Linear model Lasso Dantzig Sparsity Model selection Sign consistency
2009/9/16
We derive the l∞ convergence rate simultaneously for Lasso and Dantzig estimators in a high-dimensional linear regression model under a mutual coherence assumption on the Gram matrix of the design and...
