In statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the … Pogledajte više Suppose the data consists of $${\displaystyle n}$$ observations $${\displaystyle \left\{\mathbf {x} _{i},y_{i}\right\}_{i=1}^{n}}$$. Each observation $${\displaystyle i}$$ includes a scalar response Pogledajte više In the previous section the least squares estimator $${\displaystyle {\hat {\beta }}}$$ was obtained as a value that minimizes the sum of squared residuals of the model. However it is also possible to derive the same estimator from other approaches.
