WebMathematically the relationship can be represented with the help of following equation −. Y = mX + b. Here, Y is the dependent variable we are trying to predict. X is the dependent variable we are using to make predictions. m is the slop of the regression line which represents the effect X has on Y. b is a constant, known as the Y-intercept. WebJan 2, 2024 · The problem you seem to have is that you mix y_test and y_pred into one "plot" (meaning here the scatter() function). Using scatter() or plot() function (which you also mixed up), the first parameter are the coordinates on the x-axis and the second parameter are the coordinates on the y-axis.. So 1.) you need to one scatter() with only y_test and …
