The least squares method is used in a wide variety of fields, including finance and investing. For financial analysts, the method can help quantify the relationship between two or more variables, such as a stock’s share price and itsearnings per share (EPS). By performing this type of anal...
OLS or Ordinary Least Squares is a method used inLinear Regression for estimating the unknown parameters by creating a model which will minimize the sum of the squared errors between the observed data and the predicted one. Ordinary Least Squares method works for both univariate dataset which means...
You understand what simple linear regression is and how the least square method is used to find the best fitting line which forms the simple linear regression equation. Hopefully, you now understand one way to measure and quantify the relationship between two variables. What next? You can read ...
Most of us came to know about the method of least squares while trying to fit a curve through a set of data points. The parameters of the curve are obtained by solving a set of equations (called the normal equations). Although widely used, this approach is not foolproof and, in some ...
