Consistency of the bootstrap for asymptotically linear estimators based on machine learning [PDF]

arXiv
The bootstrap is a popular method of constructing confidence intervals due to its ease of use and broad applicability. Theoretical properties of bootstrap procedures have been established in a variety of settings. However, there is limited theoretical research on the use of the bootstrap in the context of estimation of a differentiable functional in a ...

Testing a Simple Structural Model of Endogenous Growth [PDF]

The efect of taxation on growth is embodied in a model of a small open economy with endogenous growth. The structural model is estimated on post-war panel data for 76 countries and the bootstrap is used to produce the model’s sampling variation.

Bootstrap Model Averaging

Model averaging has gained significant attention in recent years due to its ability of fusing information from different models. The critical challenge in frequentist model averaging is the choice of weight vector. The bootstrap method, known for its favorable properties, presents a new solution.

Model Selection by Bootstrap Penalization for Classification [PDF]

Machine Learning, 2004
We consider the binary classification problem. Given an i.i.d. sample drawn from the distribution of an \(\mathcal{X}\times\{0,1\}\)-valued random pair, we propose to estimate the so-called Bayes classifier by minimizing the sum of the empirical classification error and a penalty term based on Efron’s or i.i.d.

Wild bootstrap of the mean in the infinite variance case [PDF]

It is well known that the standard i.i.d. bootstrap of the mean is inconsistent in a location model with infinite variance (?-stable) innovations. This occurs because the bootstrap distribution of a normalised sum of infinite variance random variables ...

Growth of Omnichannel Grocery Retailing and Food Prices

Agribusiness, EarlyView.
ABSTRACT This paper examines the effects of the growth of omnichannel grocery retailing on food prices. We first develop a conceptual model of consumer choice and retailer pricing that allows us to evaluate changes in equilibrium prices, quantities, and profits with online channel growth and alternative pricing strategies.
