多重线性回归(Multiple Linear Regression) 多重线性回归将会不只有一个自变量,并且每个自变量拥有自己的系数且符合线性回归。 在建立多重线性回归之前,有这么几个前提必须要注意一下,这些有助于你判断数据是否适合使用多重线性回归: 1, 线性(linearity) 2, 同方差(Homoscedasticity) ...
Multiple linear regression (MLR) analysis according to least-squares procedures is normally applied to estimate model equation coefficients. Many researchers have conducted studies on UHPC materials, the effects of additives on concrete durability, and compressive strength. Charhate et al.35used ANN and...

Linear vs. Multiple Regression Ordinary linear squares(OLS) regression compares the response of a dependent variable given a change in some explanatory variables. However, a dependent variable is rarely explained by only one variable. In this case, an analyst uses multiple regression, which attempts ...
