Quantitative Measures

1. Simple running(a) reverting Model See Page 1 for the Data used to create this Simple get outar fixation turnout a) Scatter Diagram The above scatter draw shows a ordained consanguinity between apple Inc. piece of land determine and pretension rates, which is also confirmed by a positive pompousness coefficient in the regression railroad siding. This outcome was expect since Inflation is depict as an join on in the toll level of ecumenic goods and services, which is faithfully represented when apple Inc. component part prices were in the $50-200 range, pretentiousness was negative... and as Inflation rates began to increase so did apple Inc. share prices. b) See Page 3 for Simple Linear Regression Computer Output c) Line panorama Plot The Line Fit plot for apple Inc. share prices shows that the majority of data points do not release on or near the predicted line. This would fate that Inflation is not a profound indicator o f Apple Inc. share price (not taking into consideration separate factors much(prenominal) as R2 or p-values). A regression model other than the linear model may produce better results d) earth the Regression Equation and allow off the meaning of each of the coefficients Yi= Apple Inc Share set X1 = Inflation Rate Yi=183.58 + 39.

49INFL For every 1% increase in Inflation, Apple Inc. share price increases by $39.49 e) State and excuse the meaning of R-Squared R2 (coefficient of determination) is used to measure goodness of fit, smell at the variation of Y around its mean (Y-bar) explained by the regression equation represented as a p! ercentage. A perfect fit (all points falling on the line) would have an R2 of 1.0, whereas an equation with an R2 of 0 would show there to be no race between the X and Y variables. This particular regression output has an R2 of .458186, which suggests the relationship is not world-shattering, but a p-value of 4.22379E-06 suggests there is significant relationship. R2 of .5 can be considered a good fit with...If you want to get a full essay, order it on our website: OrderCustomPaper.com
