Morphology
The phrase is a straightforward composition: an 'equation' that expresses a 'regression' (a statistical relationship used for prediction). Although the concept is technical, the meaning follows directly from the constituent words and is cross‑linguistically paralleled in other languages, so a learner who knows both words can infer the MWE's sense.
Etymology
Regression equation comes from regression, a word that meant 'going back' toward the 'average' of a group of numbers. The equation is the simple rule that finds the best line through the points on a graph, and that line helps you predict one value from other values.
