French Equivalent: Variable indépendante

This term is regularly used in contradistinction to “dependent variable” in regression analysis. When a variate y is expressed as a function of variables x1, x2, …………, plus a stochastic term the x’s are known as “independent variables”.

The terminology is rather unfortunate since the concepts has no connection with either mathematical or statistical dependence. Modern usage prefers “explanatory variable”, “predicated variable” or, best of all, “regressor”.
