Unformatted text preview: MIE360 Computer Modeling and Simulation Lecture Notes Daniel Frances © 2010 1 Lecture 11 – Comparing Two Alternatives Suppose you • carry out an initial trial of 5 runs with the following results: 9.29, 2.14, 6.57, 11.14, & 12.57. • then make a single change to your model, e.g. you increase the resources. • again run with a trial of 5 runs, and obtain the following results: 8.32, 5.34, 5.18, 8.25, and 7.32. We can tabulate the results and as we did when comparing actual and simulated results, we need to consider TWO different confidence intervals for the difference between the means: the paired-t based on the pairwise differences, and Welch’s confidence interval based on the ugly d.f. formula i X Y X-Y 1 9.29 4.32 4.97 2 2.14 7.94-5.80 3 6.57 5.18 1.39 4 11.14 10.20 0.94 5 12.57 7.32 5.25 mean 8.34 6.99 1.35 stdev 4.13 2.33 4.46 Before we proceed we should ask ourselves can there be a correlation between the two sets of data....
