Endogenous variables are important in econometrics and economic modeling because they show whether a variable causes a particular effect. Economists employ causal modeling to explain outcomes (dependent variables) based on a variety of factors (independent variables), and to determine to which extent a result can be attributed to an endogenous or exogenous cause.
'''Exogenous''' (or exogeneous) (from the [[wiki/Greek language|Greek]] words "exo" and "genis", meaning "outside" and "generated") refers to an action or object coming from outside a system. It is the opposite of [[wiki/Endogenous|endogenous]], something generated from within the system.
The independent variable is the value being manipulated or changed, while the dependent variable is the observed result of the independent variable being manipulated. "IF" you change the independent variable, "THEN" what happens to the dependent variable?
1-Endogenous antigens(En.A) originate by the multiplication of pathogen inside the antigen presenting cell, such as pathogen is intracellular multiply in cytoplasm. 2-En.A presented via M.H.C1 molecule recognized by the CD8 and T-lymphocytes. 3-It includes viral and tumor antigens. 1-Exogenous antigens (Ex.A) originates outside and taken by antigen presenting cells when extracellular pathogen are engulfed and kill inside the phagolysosome. 2-Ex.A presented via M.H.C2 molecule recognized by CD4 and T-Lymphocytes. 3-It includes allergens,bacteria structures (like capsule, flagella e.t.c).

The endogenous variables value is established by the conditions of the other variables in the structure. The exogenous variables value in independent of the conditions of the other variables in the structure. The difference between the endogenous and exogenous variables is the endogenous depends solely on the structure and the exogenous depend on outside elements.

Endogenous is internal, biological and somatic Exogensous is externally caused - environmental
Endogenous disease is when the cause is within the body and not outside the body.(eg. appendicitis) Exogenous disease has trigger source outside the body. (eg. infections)

The distinction between these two types of variables is whether the variable regress on another variable or not. Like in a linear regression the dependent variable (DV) regresses on the independent variable (IV), meaning that the DV is being predicted by the IV. Within SEM modelling this means that the exogenous variable is the variable that another variable regresses on. Exogenous variables can be recognized in a graphical version of the model, as the variables sending out arrowheads, denoting which variable it is predicting. A variable that regresses on a variable is always an endogenous variable even if this same variable is used as an variable to be regressed on.
Any activity which is occurring outside the system ,and that particular activity also affect the system is known as exogenous activity whereas endogenous activity are those activity that occur within the system ,and also affecting the system.
'''Exogenous''' (or exogeneous) (from the [[wiki/Greek language|Greek]] words "exo" and "genis", meaning "outside" and "generated") refers to an action or object coming from outside a system. It is the opposite of [[wiki/Endogenous|endogenous]], something generated from within the system.
Endogenous processes are those that are internally driven by an organism, system, or entity, while exogenous processes are external factors that influence the system from outside. Processes that directly conflict with exogenous processes are typically those that originate within the system and contradict or resist the external influences. This can lead to a struggle for control or dominance between internal and external factors.
Predetermined variables are determined by factors in the past and cannot be changed, while exogenous variables are determined by factors outside the model being analyzed. Predetermined variables are considered to be endogenous in the context of a model, while exogenous variables are considered to be exogenous.
The independent variable is the value being manipulated or changed, while the dependent variable is the observed result of the independent variable being manipulated. "IF" you change the independent variable, "THEN" what happens to the dependent variable?
