Web26 sep. 2024 · My regression model takes in two inputs (critic score and user score), so it is a multiple variable linear regression. The model took in my data and found that 0.039 and -0.099 were the best coefficients for the inputs. For my model, I chose my intercept to be zero since I’d like to imagine there’d be zero sales for scores of zero. Web1 jul. 2024 · To find out the predicted height for this individual, we can plug their weight into the line of best fit equation: height = 32.783 + 0.2001* (weight) Thus, the predicted height of this individual is: height = 32.783 + 0.2001* (155) height = 63.7985 inches. Thus, the residual for this data point is 62 – 63.7985 = -1.7985.
