Key Differences
Break down "regressor" into its components: regress + or, where "or" signifies the one who performs a function.
Connect "regressor" to other statistical terms that end in "-or," such as "predictor" or "operator," to reinforce the correct suffix.
"Regressor" ends with "-or," a common suffix for nouns indicating an agent or doer, similar to "actor" or "creator."
The suffix "-and" in "regressand" is uncommon and not typically used to describe roles or agents, unlike "-or."
Recall that "regression" refers to the statistical method, and "regressor" is derived directly from it, maintaining the root "regress-."
