B 2 8 2 Divide both sides of the equation by 8 b 2 8 8 2 8 b 2 2 8. We use the Least Squares Method to obtain parameters of F for the best fit. B square root of 1 4.
Further regression analysis can provide an estimate of the magnitude of the impact of a change in one variable on another.
While only 588 of the variability in population can be explained by the linear relationship almost 91 of the variability can be explained by the exponential relationship. Y ae bx Where a and b are calculated coefficients and e is the mathematical constant e the base of the natural logarithm. 23571113 Enter Y Values Eg114 17 273 361 477 499. In order for it to be exponential you need a common ratio and a starting value when x 0 so going from 1st to 2nd term 63 2 2nd to 3rd term 126 2 so you have a common ratio of 2.
