This test in fact aims to approve the absence problematic multicollinearity, which inflates the standard deviations (the variance square root) for the exogenous variables and makes the significant tests (T-statistic tests) for those variables unreliable.
Two of the indicator exogenous variables are directly associated with the endogenous indicator variable.
As exogenous variables, government support, perceived risk, and education attainment influence subjective norms, PEU, and PU.
In order to test the significance impact of the exogenous variables on the HHI for Norwegian imports to the continent of North and Central America, we fit a regression model that is summarized in Figure 1.
Drawing on the discussion in this article, three principal conditions can be identified: (1) unilateral leadership from the United States or China; (2) coalition leadership from the BRICS; and (3) an exogenous variable to shift the behavior of the United States, China, or the BRICS.
Table 4 presents the results of one, two, and three-month ahead forecasts of the futures price using a VAR model with the spot price as an exogenous variable.
First, in almost all cases where there were statistically-significant relationships between exogenous variables and awareness, the absolute differences in awareness across categories of individual characteristics (e.
We will compare the wind speed and power forecast efficacy (at WT24) for two different NARX ANN models, namely, (1) a NARX(0, 0) ANN model (namely, p = q = 0 in which the dependent variable at a given time depends only on the current value of the exogenous input) and (2) the optimal NARX(p, q) ANN model with p [member of] {1,2} and q [member of] {1,2} allowing for the modeling of a possible temporal correlation structure in the previous dependent and current and previous exogenous variables used for the wind speed and power forecasting.
Next, replace in the previous expression all realizations of exogenous variables with the equations of system (B) accordingly to each variable to verify:
In this example, all variables that are effected by other variables--social norms and amount of smoking--are endogenous variables, while variables that only impart an effect on other variables without being effected by other variables--the prevention program--are exogenous variables.
During modeling, each modeller should also take into account exogenous variables of the system, which should be regarded as a relatively independent of the explored system.
To determine the relationship of these variables a MANOVA was conducted to explore any possible multivariate relationship between placement restrictiveness and the exogenous variables.
