WebApr 10, 2024 · This result exhibits a well-fitted prediction, which can be described by raising the highest fitness coefficient of R 2 = 0.9309. In contrast, the linear regression model has more distant data points against the expected result, representing poor prediction. This result can be explained numerically by gaining the lowest R 2 value, … WebThe line of best fit to show the relationship between variables, the one that minimizes distance from each data point to the line. y = mx^2 + b. True or False? false. This is not the form that a linear regression equation takes. Linear regression is always of degree 1, so the exponent of 2 associated with the x makes this a non-linear equation.
