regression equation,regression of y on x- the equation representing the relation between selected values of one variable (x) and observed values of the other (y); it permits the prediction of the most probable values of y regression curve,regression line- a smooth curve fitted to the set of...
如果你以前学过线性回归,你可能认为这个函数和最小均方损失函数(least-squares cost function )很类似,并提出普通最小二乘法回归模型(ordinary least squares regression model)。 三、普通最小二乘法(ordinary least squares) 最小二乘法(又称最小平方法)是一种数学优化技术,它通过最小化误差的平方和寻找数据的最...
Once obtained, those values of α and β, which minimize the squared errors, our model’s equation will look like this:Linear regression model equation. | Image: Valentina Alto An introduction to ordinary least squares (OLS) in linear regression. | Video: XLSAT ...
Let’s plug the slope and intercept values in the ordinary least squares regression line equation: y = 11.329 + 1.0616x This linear equation matches the one that the software displays on the graph. We can use this equation to make predictions. For example, if we want to predict the score ...

Ordinary least squares regression is also known as ordinary least squares or least squared errors regression. Techopedia Explains Ordinary Least Squares Regression Invented in 1795 by Carl Friedrich Gauss, it is considered one of the earliest known general prediction methods. OLSR describes the relationsh...
II.I.2 Ordinary Least Squares for Simple Regression Assume the following relationship should be investigated by means of simple linear regression the influence of the interest rate on the demand of newprivatecars. If the researcher has two equally ranged time series, R for interest rate) and C...
