This volume, edited by Jeffrey Racine, Liangjun Su, and Aman Ullah, contains the latest research on nonparametric and semiparametric econometrics and statistics. These data-driven models seek to replace the classical parametric models of the past, wh

We propose ℓ2-relaxation, which is a novel convex optimization problem, to tackle forecast combination with many forecasts or minimum variance portfolio with many assets. ℓ2-relaxation minimizes the squared Euclidean norm of the weight vector sub

This paper proposes a model-free test for the strict stationarity of a potentially vector-valued time series using the discrete Fourier transform (DFT) approach. We show that the DFT of a residual process based on the empirical characteristic functio

We consider the estimation and inference in approximate factor models with random missing values. We show that with the low rank structure of the common component, we can estimate the factors and factor loadings consistently with the missing values r

A PointNet-based data-driven neural network model is proposed, which takes the film hole geometry variables and flow conditions as inputs to reconstruct the adiabatic cooling effectiveness distribution. The model aims to realize rapid reconstruction

Turbine cooling is an effective way to improve the comprehensive performance and service life of gas turbines. In recent decades, there has been rapid growth in research into external cooling and internal cooling methods. As a result, there is a sign
