GROUP #1 Group Work #1 A. development HTWT1 info set, rejoinder the questions below. a. Plot the each observation on the chart b. fly the coop the estimated regression line on the graphical record c. Write elaborate the speculative equation of Y ( pitch) as a matter of X (height) Yi = ?0 + ?1Xi +?i d. development SPSS, run a regression and obligate e. discover The coefficient,means that weight equals 103.393 when height equals 0. However, this conclusion is unjustified imputable to some(prenominal) reasons. Therefore, it is much better to understand the coefficient as slide altering more than the value of the estimated regression when x1=0 or to non attend the coefficient at all. The coefficient,means that if height gains by 1 unit, weight would increase by 6.377 units. Therefore, the coefficient exercises the change in height jibe with a one unit change in height. f. Using transcend or the sheet attached, calculate the predicted weight g. Using go by or the sheet attached, calculate the residual h. intercommunicate top 4 highest residuals (regardless of its sign) on the graph B. Using EX1 data set, rejoinder the questions below. i. Plot each observation on the graph j. Suppose the on-key ?0 equals 0 and the true ?1 equals 1.5. Write down the notional equation of Y as a function of X.

(Note: Usually, we do not know true value of theoretical equation. However, we assume it because we want to understand the differences surrounded by the error m arches and the residual.) k. dr! ag out this theoretical equation on the graph l. Using excel or the sheet attached, calculate the error term (? ) and set up them on the graph m. Using SPSS, run a regression and nurse estimated coefficients, n. Draw this estimated regression equation on the graph o. Using Excel or the sheet attached, calculate the...If you want to get a full essay, order it on our website: OrderEssay.net
