Plain explanation
Example
A model estimates a home’s energy use from floor area, insulation, weather, and occupancy patterns.Why it matters
Many decisions rely on numerical estimates rather than categories. Evaluation must examine error size, distribution, subgroups, uncertainty, and whether the relationship remains valid in the intended setting.Common misunderstanding

Defines regression as prediction of numerical values; statistical uses of the term may involve additional interpretation and assumptions.
