Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Assessing Eco‐Efficiency in Municipal Solid Waste Management Integrating Heterogeneity: A Latent Class Stochastic Frontier Analysis

Sustainable Development, EarlyView.
ABSTRACT The measurement of eco‐efficiency in the municipal solid waste (MSW) sector has garnered significant attention due to the substantial environmental impacts of unsustainable MSW management and the high operational costs associated with public service provision.

A stochastic frontier regression model with dynamic frontier

Communications in Statistics - Simulation and Computation, 2020
We consider a stochastic frontier regression model with a time dependent efficiency process, which is assumed to follow an exponential autoregressive sequence.
