If I have a regression or classification problem
y ~ x1 + x2 + ... + xn
I might call the xi
the regressors or the predictors. But what do you call y
?
The terms regressand and predictand are clunky, don't seem particularly standard, and have the disadvantage that they're very similar to the words for the right-hand-side variables (I'm going to be using these terms in type declarations and documentation for a program, so minimizing the potential for confusion is a priority).
Also, using regressor and regressand is inappropriate when you have a classification problem, rather than a regression.
Is there a commonly used term?

The "response" or "outcome" variables are commonly used terms.
