At its core, Least Squares Estimation is a linear regression technique that minimizes the sum of the squared errors between observed and predicted values. This method uses the least amount of data required to fit a linear relationship between variables. Think of it as finding the best straight line to represent a set of scattered points.

In the US, Least Squares Estimation is being widely adopted in fields such as finance, healthcare, and marketing. The technique is particularly useful in financial modeling, where it helps predict stock prices and analyze market trends. Additionally, healthcare organizations are using it to develop personalized treatment plans and improve patient outcomes.
