BU275 Lecture Notes - Lecture 9: Null Hypothesis
Document Summary
Decide: ex. balking, reneging, can use probabilities or conditions. *use tools expression builder to help build a formula to input. Assign: set a value for prioritization or characteristics. For customer surveys, can use a delay process model. Tools, input analyzer. can examine data points, plot on histogram. Fit can choose distribution, see how well it fits can copy expression into arena to simulate this information the higher the p-value, the better, want to not reject null hypothesis. Fitting data to distributions use the squared error to find a set of candidates (lowest ones) define the candidates using chi-squared and kolmogorov-smirnov test statistics and p- value (want a small t-stat and large p-value) Want a p-value > . 5 for chi-squared and a t-stat < . 03 for kolmogorov-smirnov. Can have two different arrivals if they are distributed differently. Can assign shopping times, priority, attributes females: shopping time = 4 + gamm(8. 5), priority 3. Males: shopping time = norm(7,3), priority 2.
