regression analysis,   etc   ; models; vegetation;     Show all 3 Subjects
Abstract:
... Foredunes in arid coastal dune systems comprise nebkhas, which originate by interactions between vegetation and aeolian sedimentation. While continuous foredunes in temperate climates have been widely studied, knowledge of interactions between biotic and abiotic drivers in foredunes formed by nebkha is still scarce. With the aim of exploring variables affecting arid foredunes, a range of morpholog ...

Abstract:
... Consumers can procure renewable energy via subscribing to green electricity from their utility for a price premium (or virtual option) or installing residential solar (or physical option). From economic theory, these options can be framed as substitutes (choosing between) or complements (choosing both). To test for this relationship, this study estimates how subscriptions to green electricity infl ...

Abstract:
... ℓ1‐penalized quantile regression (QR) is widely used for analysing high‐dimensional data with heterogeneity. It is now recognized that the ℓ1‐penalty introduces non‐negligible estimation bias, while a proper use of concave regularization may lead to estimators with refined convergence rates and oracle properties as the signal strengthens. Although folded concave penalized M‐estimation with strongl ...

Abstract:
... Much of the analysis of panel data has been based on an assumption of strict exogeneity.

The paper relaxes this assumption in order to al ...
