👉 Exogamies, also known as exogenous variables, are variables that are introduced into a model to explain or predict the outcome of the dependent variable. These variables can be either quantitative or qualitative in nature and may vary from one study to another. For example, in econometrics, exogamies might include things like income levels, education level, race, gender, age, etc., which are used as inputs into a model that attempts to predict an individual's income or educational attainment.
