The IQ Experiment
Pfeifer, Phillip E.; Ovchinnikov, Anton S.Case DARDEN-QA-0770-EDecision AnalysisThis case describes an IQ experiment in which 66 students, under the direction of their professor, used Excel to generate simulated IQs. The instructions were such that the generated IQs should have come from a normal distribution with a mean of 100 and standard deviation of 15. The sample average IQ, however, was 104.3. Students are asked to use their data-analysis skills to make sense of the results. The data set also contains gender (male or f...Starting at €8.20

FLORA (B): National
Bodily, Samuel E.; Ovchinnikov, Anton S.Case DARDEN-QA-0755-EDecision AnalysisIn this, the second of a two-case decision analysis series, an entrepreneur must decide whether there are additional benefits from operating in more than one U.S. city. He explores the business model of operating local production facilities in major cities, metro areas with a population of over one million. Going national in year three would allow for a year four launch. Again, the entrepreneur must choose between a discounted and a premium strat...Starting at €5.74

Timeshare Exchange Fair (A)
Ovchinnikov, Anton S.; Sampson, Scott E.; Krass, DmitryCase DARDEN-QA-0709-EDecision AnalysisThis award-winning case series examines how optimization-based decision-making leads to a new business design for a timeshare exchange: an exchange fair. Students model a complex managerial problem as a linear program, identify the types of data needed, and use models to provide decision support. The series covers linear and integer programming, multiple-criteria decision-making, network flow problems, local search heuristics, and Pareto-optimali...Starting at €8.20

Timeshare Exchange Fair (B)
Ovchinnikov, Anton S.; Sampson, Scott E.; Krass, DmitryCase DARDEN-QA-0710-EDecision AnalysisThis case provides an extension of the A case (UVA-QA-0709) by including two types of owners' requests that were omitted in the A case for simplicity. Solving it requires knowledge of integer programming and how it can be used to reinforce logical conditions. Could be used as an assignment or part of an exam. A supplemental Excel spreadsheet is available (UVA-QA-0709X).Starting at €5.74

Modeling Discrete Choice: Categorical Dependent Variables, Logistic Regression, and Maximum Likelihood Estimation
Ovchinnikov, Anton S.Technical Note DARDEN-QA-0779-EDecision AnalysisThis technical note introduces business students to the concepts of modeling discrete choice (e.g., a consumer purchasing brand A versus brand B) using logistic regression and maximum-likelihood estimation. It draws the analogy between modeling discrete choice and building a regression model with a dummy dependent variable and on an example illustrates the need for estimating the probability of a choice rather than the choice itself, which leads ...Starting at €8.20
