endogenous variable in a sentence

Examples

1. Instrumental variables, for example, attempt to model the endogenous variable " X " as an often invertible model with respect to a relevant and exogenous instrument " Z ".
2. That is, if we consider a sufficiently small change in some exogenous parameter, we can calculate how each endogenous variable changes using only the first derivatives of the terms that appear in the equilibrium equations.
3. For an equation in a system of equations to be identified, the number of excluded exogenous variables in that equation must be at least as great as the number of included endogenous variables, less one.
4. The test statistic can be computed from chi-square variable with ( m-k ) degrees of freedom ( where m is the number of instruments and k is the number of endogenous variables ).
5. The survey questions measured the different aspects of the TRA model : behavioral beliefs, outcome evaluations, attitude toward the behavior, normative beliefs, motivation to comply, subjective norms, and the consequence endogenous variable.
6. Thus, the occurrence of one structural shock " ? i, t " can potentially lead to the occurrence of shocks in all error terms " e j, t ", thus creating contemporaneous movement in all endogenous variables.
7. Then, we can use ( z 1, z 2, z 3 ) as instruments to estimate the coefficients in the above equation since there are one endogenous variable ( y 2 ) and one excluded exogenous variable ( z 2 ) on the right hand side.
8. Internal risks arise from factors ( endogenous variables, which can be controlled ) such as human factors ( talent management, strikes ), technological factors ( emerging technologies ), physical factors ( failure of machines, fire or theft ), operational factors ( access to credit, cost cutting, advertisement ).
9. The " rank condition " of identifiability is that " n i " } }, where ? " i " 0 is a matrix which is obtained from ? by crossing out those columns which correspond to the excluded endogenous variables, and those rows which correspond to the included exogenous variables.
10. Judea Pearl defines a causal model as an ordered triple \ langle U, V, E \ rangle, where U is a set of exogenous variables whose values are determined by factors outside the model; V is a set of endogenous variables whose values are determined by factors within the model; and E is a set of structural equations that express the value of each endogenous variable as a function of the values of the other variables in U and V.
