Curve Fitting in Python
Curve fitting is a statistical method used to establish a mathematical relationship between a set of data points and a continuous function. The goal is to find the best-fitting curve that approximates the data, allowing for predictions and analysis of trends. In this article, we will explore the concept of curve fitting, its underlying statistical…
