Morphology
The noun phrase is compositional: 'linear' specifies the type of 'regression' (a regression that uses a linear function/equation), so the overall meaning follows directly from the constituents. This adjective+noun pattern is regular and cross-linguistically common in scientific vocabulary, making the term immediately understandable to learners who know both component meanings, despite its technical nature.
Etymology
The phrase linear regression comes from the image of drawing a straight line through many scattered points: linear means 'straight' and regression here means finding the line that best fits those points. That's why the term means 'using a straight line to show or predict the relationship between things'.
