regression analysis
Regression analysis is the statistical fortune-teller that touts, "The future must be this!" after scrutinizing every scrap of past data. In reality, it is a hapless prophet, tossed about by noise and changing predictions at the slightest sample tweak. Armed with formulas like magical circles, it boldly claims correlation guarantees causation. It listens for whispers of the dependent variable while arranging a parade of excuses called residuals. In business meetings, it dons the mantle of authority through ornate graphs, the office's top charlatan of the future.
