Correlated Errors Challenge Vulnerable Growth
We examine the impact of correlated errors on findings regarding fluctuations in US GDP growth, which are primarily driven by the lower quantiles of the distribution as predicted by financial conditions. A proposed zero‐correlation test reveals the presence of correlated residuals in the quantile regression, introducing endogeneity and raising concerns about the validity of the previous analysis. In response, we extend the model by including two …
A Random Forest–Based Panel Data Approach for Program Evaluation
It is challenging to conduct controlled experiments to assess the impacts of social policy. To address this, past studies propose a panel data approach using factor models to estimate average treatment effects. The selection of control units is a critical step to balance the goodness of fit within‐sample with the posttreatment forecasting error when the number of observed potential control units is large. In this study, we propose using random fo…
Varietal-specific growth performance and ecological restoration Potential of Olea europaea L. in Abandoned Mine Slags
Mine ecological restoration is an important means of improving the ecological environment of abandoned mining areas, and the selection and configuration of plant species play a critical role in the restoration outcomes. This study aims to investigate the effects of different types of mining slag on the growth performance and survival rate of olive cultivars, providing a scientific basis for mine ecological restoration. The experimental results in…
Platelet counts affect the association between hyperhomocysteinemia and pregnancy complications
Among Chinese pregnant women, one subgroup (high tHcy and low PC) has the highest risk of ICP and another (high tHcy and high PC) has the lowest risk of GDM; tHcy and platelet could be used as indicators to identify the women with high risk of ICP or low risk of GDM
Decreased CO2 Levels as Indicators of Possible Mechanical Ventilation-Induced Hyperventilation in Covid-19 Patients
Background: Six months since the outbreak of coronavirus disease (COVID-19), the pandemic continues to grow worldwide, although the outbreak in Wuhan, the worst-hit area, has been controlled. Thus, based on the clinical experience in Wuhan, we hypothesized that there is a relationship between the patient's CO 2 levels and prognosis. Methods: COVID-19 patients' information was retrospectively collected from medical records at the Leishenshan Hospi…
Semiparametric estimation and variable selection for single‐index copula models
A copula with a flexibly dependence structure can capture complexity and heterogeneity in economic and financial time series. Based on the recently proposed single‐index copula, we propose a simultaneous variable selection and estimation procedure. This method allows for choosing the most relevant state variables by using a penalized estimation with large sample properties derived. Simulation results demonstrate the good performance of the method…
