In regression analysis, the linear equation that approximately represents the distribution of points on a coordinate plane where pairs of observed values of x and y are plotted as points. It is expressed as a linear equation y = ax + b , and a and b can be found using the least squares method. Regression equation. Source: About Shogakukan Digital Daijisen Information | Legend |
回帰分析において、x、yの観測値の組を点に記した座標平面上で、それらの点の分布を近似的に表す直線の方程式。一次式y=ax+bで表され、最小二乗法を用いて、a、bが求められる。回帰方程式。
