The method of fitting first-order models is the same as that of fitting the simple straight-line
model, i.e. the method of least squares.

Question

Quizplus · Accepted Answer

First-order models are essentially simple straight-line models (linear models) where the method of least squares is used to minimize the sum of the squared differences between the observed values and the values predicted by the model.
