    Who is this topic relevant for?

  • Assuming a perfect curve: Least squares curve fitting doesn't aim to create a perfect curve but rather an optimal one that trades off between accuracy and complexity.

    • Curve fitting is a fundamental concept in statistics and mathematics that involves finding the best-fitting curve or surface to a given set of data points. Least squares curve fitting is a specific type of curve fitting method that seeks to minimize the sum of the squared errors (SSE) between observed data points and the fitted curve. This is achieved by adjusting the parameters of a mathematical model to reduce the sum of the squared differences between the data points and the predicted values.
