Is Smoking Inferior?:Evidence from Variation in the Earned Income Tax Credit
Smoking Variation Earned Income Tax Credit
2016/3/3
In this paper we estimate the causal income elasticity of smoking participation, cessation, and cigarette demand conditional upon participation. Using an instrumental variables (IV) estimation strateg...
An ADMM Algorithm for a Class of Total Variation Regularized Estimation Problems
Signal processing algorithms stochastic parameters parameter estimation
2015/7/9
We present an alternating augmented Lagrangian method for convex optimization problems where the cost function is the sum of two terms, one that is separable in the variable blocks, and a second that ...
Quantitative bounds for Markov chain convergence: Wasserstein and total variation distances
convergence rate coupling Gibbs sampler iterated random functions local
2011/3/24
We present a framework for obtaining explicit bounds on the rate of convergence to equilibrium of a Markov chain on a general state space, with respect to both total variation and Wasserstein distance...
Joint and Individual Variation Explained (JIVE) for Integrated Analysis of Multiple Datatypes
Vertical integration Multi-block data Principal Component
2011/3/24
Research in a number of fields now requires the analysis of "multi-block" data, in which multiple high-dimensional, and fundamentally disparate, datatypes are available for a common set of objects. In...

On the Regular Variation of Ratios of Jointly Frechet Random Variables
Regular variation multivariate Frechet distribution spectral
2011/3/18
We provide a necessary and sufficient condition for the ratio of two jointly alpha-Frechet random variables to be regularly varying. This condition is based on the spectral representation of the joint...
Coarse-grained modeling of multiscale diffusions：the p-variation estimates
parameter estimation multiscale diffusions p-variation Ornstein-Uhlenbeck
2010/3/10
We study the problem of estimating parameters of the limiting equation
of a multiscale diffusion in the case of averaging and homogenization, given
data from the corresponding multiscale system. Fir...

2010/3/9
Hidden regular variation defines a subfamily of distributions satisfying multivariate
regular variation on E = [0,1]d\{(0, 0, · · · , 0)} and models another regular variation on the sub-cone E(2) = E...

A representation theorem for continuous additive functionals of zero quadratic variation
A representation theorem continuous additive functionals zero quadratic variation
2009/9/22
We study continuous additive functionals of zero
quadratic variation of strong Markov continuous local martingales by
means of stochastic calculus. We show that they admit a representation
as a sto...

CONVERGENCE IN VARIATION OF THE JOINT LAWS OF MULTIPLE STABLE STOCHASTIC INTEGRALS
Convergence in variation multiple stochastic integrals stable process LePage representation
2009/9/18
In this note, we are interested in the regularity in the sense
of total variation of the joint laws of multiple stable stochastic integrals.
Namely, we show that the convergence
