python - Is there a way to perform multioutput regression in …
NettetLinear regression uses the least square method. The concept is to draw a line through all the plotted data points. The line is positioned in a way that it minimizes the distance to all of the data points. The distance is called "residuals" or "errors". The red dashed lines represents the distance from the data points to the drawn mathematical ...

NettetI am implementing regression. 我正在实施回归。 Output_variable is my y variable and input2, input4, Input5&1, input6-3 are x variables in my regression equation. Output_variable 是我的 y 变量,而 input2、input4、Input5&1、input6-3 是我的回归方程中的 x 变量。 All these are basically columns in df.
