Baseline zone estimation in two dimensions

Atul Mallik, Moulinath Banerjee, Michael Woodroofe

We consider the problem of estimating the region on which a non-parametric regression function is at its baseline level in two dimensions. The baseline level typically corresponds…

Bootstrap confidence intervals for isotonic estimators in a stereological problem

Bodhisattva Sen, Michael Woodroofe

Let be a spherically symmetric random vector of which only can be observed. We focus attention on estimating F, the distribution function of…

Inconsistency of bootstrap: The Grenander estimator

Bodhisattva Sen, Moulinath Banerjee, Michael Woodroofe

In this paper, we investigate the (in)-consistency of different bootstrap methods for constructing confidence intervals in the class of estimators that converge at rate .…

Streaming motion in Leo I

Bodhisattva Sen, Moulinath Banerjee, Michael Woodroofe +2

Whether a dwarf spheroidal galaxy is in equilibrium or being tidally disrupted by the Milky Way is an important question for the study of its dark matter content and distribution.…

Clean Kinematic Samples in Dwarf Spheroidals: An Algorithm for Evaluating Membership and Estimating Distribution Parameters When Contamination is Present

Matthew G. Walker, Mario Mateo, Edward W. Olszewski +2

(abridged) We develop an algorithm for estimating parameters of a distribution sampled with contamination, employing a statistical technique known as ``expectation maximization'' (…

Velocity Dispersion Profiles of Seven Dwarf Spheroidal Galaxies

Matthew G. Walker, Mario Mateo, Edward W. Olszewski +4

We present stellar velocity dispersion profiles for seven Milky Way dwarf spheroidal (dSph) satellite galaxies. We have measured 8394 line-of-sight velocities (+/- 2.5 km/s) for 68…
