Box-Jenkins modelsIntervention analysis is a relatively new branch of time series analysis. The power of this technique, which gives the probability that changes in mean level can be distinguished from natural data variability, is quite sensitive to the way the data are collected. The principal ...
www.nature.com/scientificreports OPEN Local environmental variables are key drivers of ant taxonomic and functional beta‑diversity in a Mediterranean dryland Clara Frasconi Wendt1,2, Ana Ceia‑Hasse1,3, Alice Nunes1, Robin Verble4, Giacomo Santini2, Mário Boieiro5...
we sequentially fitted one environmental variable at a time as the explanatory variable and treated ancestry coefficients as covariates in RDA models. Considering the correlation between environmental variables (Fig. S3C and D), we conducted additional permutation tests for marginal effects of environmental...
(b) and categorical variables describing environmental contexts (c), from left to right: zone; soil moisture class; soil pH class; and vegetation type (B, barren; G, graminoid; P, prostrate shrub; S, erect shrub; W, wetland tundra). The maps were made with R. ...
In this article a class of additive models are introduced for environmental time series, in which both mean levels and variances of the series are nonlinear functions of relevant meteorological variables. Backfitting algorithms in nonlinear regression are adopted to estimate the unknown functions in the...
Table 4 Results from LASSO Exposures selected in the final model Full size table Regarding the exposures during childhood, a total of 23 variables was selected by LASSO and 16 of them were kept in the final multivariable model (p-value ≤ 10%) (Fig. 3 and Table 4). High intakes of...
In 2022, the European Union put forward the REPowerEU plan in response to Russia’s invasion of Ukraine, aiming at enhancing short-term energy security by diversifying imports and reducing natural gas demand while accelerating the deployment of renewable alternatives in the long term. Here, we qua...
Variables definitions and measurement To account for the heterogeneity of the DMBs in Nigeria, the study used ROA and Tobin’s Q (market value) as measures of financial performance. The independent variables included in the model were SSCM environmental disclosure, bank size, capital structure, an...
Latent social, governmental, responsive, and environmental engagement variables are analyzed, highlighting the complexity of urban policies and the necessity for adaptable strategies. The findings suggest that greater social and governmental engagement correlates with more favorable perceptions of river quality...
