We tested the sensitivity of wheat yield to tree-mediated variables of photosynthetically active radiation (PAR), air temperature and soil nitrogen, using APSIM-wheat model.
Despite not directly modeling the mediated pathways, LMMs excluding mediating variables performed well with respect to power, bias and coverage probability in modeling the total effect of the primary independent variable on the outcome.
For each model we calculated the mediated proportion (MP), that is, the risk reduction explained by the variables in the model according to the formula MP = (PRunmed – PRmed) ÷ (PRunmed – 1) × 100, where PRunmed and PRmed are confounder-adjusted PRs from models without (nonmediated) and with (mediated) the potential mediating variable.
This finding agrees with the results of previous research on street drug markets (Rengert et al. 2005), but the finding might be influenced by other mediated situational variables.
No potential dinucleotide-mediated phase variable CDSs were identified in the H. canadensis genome sequence data.
Likewise, the third model excluded PHFI to determine whether this variable mediated the relationship between HIV and stress.
We examine possible indirect or mediated effects of clinical variables, which may shed some light on the connection between speech and OSA.
This study suggests that the computation based on the context-mediated PDs of visual variables in natural scenes may underlie the neural mechanism in the early visual cortex for detecting salient features in natural scenes.
Despite the overt complexity of uORF-mediated translational control, several variables correlating with strong repression of MCS translation emerge from published data.
Analyses of historic and future simulation results for the identified periods show that the same median rainfall obtained by accounting for climate natural variability triggers hydrologically-mediated non-uniqueness in flow variables resolved at the hydraulic scale.
SEMs are a general modeling framework often used in the social sciences to analyze complex relationships between variables, such as mediated relationships between variables.
