Who Survived The Titanic? A Logistic Regression Analysis, Lonnie K. Stevans, David Gleicher
Who Survived The Titanic? A Logistic Regression Analysis, Lonnie K. Stevans, David Gleicher
Lonnie K. Stevans
A logistic regression analysis of an extensive data set on the Titanic passengers is presented which tests the likelihood that a Titanic passenger survived the accident--based upon passenger characteristics. The main finding is that underneath the strong overt preference afforded in the rescue by the authorities to women and children over men, there was a complex class determination of survival rates among men, on the one hand, and women and children, on the other. We hypothesize that the statistical interactions of gender and class are explained by two crucial decisions made by the ship’s authorities: 1. to encourage, and perhaps …

Organizations may view outsourcing as a way to manage risk. We developed a decision-analytic approach to determine which risks the buyer can share or shift to vendors and which ones it should bear. We found that allocating risks incorrectly could increase costs dramatically. Between 1995 and 1998, we used this approach to develop the request for proposals (RFP) for the US Department of Energy’s (DOE’s) privatization initiative for the Hanford tank waste remediation system (TWRS). In the model, we used an assessment protocol to predict how vendors would react to proposed risk allocations in terms of their actions and their …

Aggregate Consumption Spending, The Stock Market, And Asymmetric Error Correction, Lonnie K. Stevans
Lonnie K. Stevans
In this study, we show how changes in wealth resulting from unanticipated changes in the value of equity holdings begin a process whereby households alter consumption growth in order to close the gap between actual and target spending. Because of changing uncertainty or equity price volatility over the stock market cycle, we found the time path of this adjustment to exhibit near random walk behavior during stock market downturns. Conversely, during “boom” periods, e.g. when the value of equities held by households was greater than the threshold, the growth in consumer spending was quick to eliminate the disparity between actual …
