I need help on how to do this part of the assignment:
Discuss why this prediction is just an estimate
1.Give the approximate and maximum values of your prediction based off your scatter around the X value predicted for
2.Discuss the precision of your prediction by linking the strength of the relationship and the amount of scatter on the graph close to the explanatory (x data value)
3.Discuss the effect of any outliers on the analysis of the prediction made
The cubic relationship is here:
GDP.change = 2.718 + 0.1662 * ExportVolume.change + -0.006774 * ExportVolume.change^2 + 0.0001214 * ExportVolume.change^3
