A Nonparametric Efficiency Analysis of California Cotton Ginning Cooperatives

Journal of Agricultural and Resource Economics, 1993
In the spirit of Leamer's commitment to sensitivity analysis, we employ Farrell's nonparametric efficiency methodology and compare our results with those of Sexton, Wilson, and Wann.

Bayesian nonparametric analysis of reversible Markov chains [PDF]

, 2013
We introduce a three-parameter random walk with reinforcement, called the $(\theta,\alpha,\beta)$ scheme, which generalizes the linearly edge reinforced random walk to uncountable spaces.

Adaptive goodness-of-fit tests based on signed ranks [PDF]

, 2008
Within the nonparametric regression model with unknown regression function $l$ and independent, symmetric errors, a new multiscale signed rank statistic is introduced and a conditional multiple test of the simple hypothesis $l=0$ against a nonparametric ...

Consistency of cross validation for comparing regression procedures

, 2008
Theoretical developments on cross validation (CV) have mainly focused on selecting one among a list of finite-dimensional models (e.g., subset or order selection in linear regression) or selecting a smoothing parameter (e.g., bandwidth for kernel ...

Logarithmic Quantile Estimation for Rank Statistics [PDF]

, 2013
We prove an almost sure weak limit theorem for simple linear rank statistics for samples with continuous distributions functions. As a corollary the result extends to samples with ties, and the vector version of an a.s.

Statistical inference for semiparametric varying-coefficient partially linear models with error-prone linear covariates

, 2009
We study semiparametric varying-coefficient partially linear models when some linear covariates are not observed, but ancillary variables are available.

Rates of convergence for the posterior distributions of mixtures of Betas and adaptive nonparametric estimation of the density [PDF]

, 2009
In this paper, we investigate the asymptotic properties of nonparametric Bayesian mixtures of Betas for estimating a smooth density on $[0,1]$. We consider a parametrization of Beta distributions in terms of mean and scale parameters and construct a ...
