These models describe the dependence relationship between one or more continuously distributed response random variables and a set of explanatory variables or factors. Curve fitting is the way we model or represent a data spread by assigning a ‘best fit‘ function (curve) along the entire range. This method applies non-linear least squares to fit the data and extract the optimal parameters out of it.
