The Nonstationarity-Complexity Tradeoff in Return Prediction

We investigate machine learning models for stock return prediction in non-stationary environments, revealing a fundamental nonstationarity-complexity tradeoff: complex models reduce misspecification error but require longer training windows that introduce stronger non-stationarity.

Inflation Control in a CVAR Model With an Application to the Burns/Miller Period in the USA

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 803-813, August 2026.
ABSTRACT The paper addresses the problem of “how to make a nonstationary inflation rate stationary by controlling the policy instrument”. It shows that a necessary condition is a significant non‐zero element in the long‐run impact matrix. An application to US data covering the Burns/Miller periods finds a significant, but positive, long‐run impact on ...

Statistical models for the utilization process of aviation radio equipment

Aviation
The reliability of aviation equipment is a critical factor that directly influences the efficiency of tasks associated with flight operations. To assess reliability, various indicators are commonly employed, including mean time between failures, mean ...

Detecting Sparse Cointegration

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 726-741, August 2026.
ABSTRACT We propose a two‐step procedure for detecting sparse cointegration in high‐dimensional single‐equation models. First, we employ the adaptive lasso to identify the subset of integrated covariates driving the long‐run equilibrium relationship.

Detection of Nonstationarity in Peak Flow, Volume, and Duration in an Urbanizing Catchment

Mathematical and Computational Applications
Urban catchments are increasingly vulnerable to hydrologic extremes driven by land-use change and climate variability, challenging the traditional assumption of stationarity.
