The 'dependent' variable is what you measure, i.e., it depends on the independent variable. The 'coefficients' are the parameters that the fitting algorithm estimates.. For example, if you have census data, then the year is the independent variable because it does not depend on anything.

For linear-algebraic analysis of data, "fitting" usually means trying to find the curve that minimizes the vertical ( y -axis) displacement of a point from the curve (e.g., ordinary least squares ). See more Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints.

In mathematics, a spline is a special function defined piecewise by polynomials. In interpolating problems, spline interpolation is often preferred to polynomial interpolation because it yields similar results, even when using low degree polynomials, while avoiding Runge's phenomenon for higher degrees.
