endogeneity
Technical term used in economics, statistics, and related fields to describe a variable that is correlated with the error term in a model, often due to simultaneity, omitted variables, or measurement error.

If you don't account for the endogeneity problem, the estimation results will be biased.
The instrumental variable method is a typical technique for dealing with endogeneity.
Compound of 内生 (endogenous) + 性 (-ness, property). The term is a direct translation of the English 'endogeneity' and is used primarily in academic contexts.
