In regression analysis, curve fitting is the process of specifying the model that provides the best fit to the specific curves in your dataset. Curved relationships between variables are not as straightforward to fit and interpret as linear relationships. For linear relationships, as you increase the independent variable by one unit, the mean ... The key to curve fitting is the form of the mapping function. A straight line between inputs and outputs can be defined as follows: y = a * x + b. Where y is the calculated output, x is the input, and a and b are parameters of the mapping function found using an optimization algorithm.Jan 7, 2024 · The term “best fit” means that the line is as close to all points (with each point representing both variables for a single person) in the scatterplot as possible, with a balance of scores above and below the line.
