Eliciting and Evaluating Expert Forecasts
Lichtendahl, Kenneth C. Jr.Technical Note DARDEN-QA-0734-EDecision AnalysisThis note emphasizes the idea that managers will often want to ask experts to express their opinions about important business risks using the precise language of probability. Examples are drawn from the 2008 financial crisis and involve value-at-risk financial reporting. The second half of this note explains how a manager might use a scoring rule to evaluate the quality of experts' probability forecasts. This note is intended to accompany an inst...Starting at €8.20

Google Cloud Platform: BigQuery Explainable AI
Lichtendahl, Kenneth C. Jr.; Boatright, BenjaminTechnical Note DARDEN-QA-0943-EDecision AnalysisMachine-learning (ML) models have become a common tool used across a multitude of industries to help people make decisions. As these models have increased in predictive power, many have also grown in complexity. The pursuit to improve the accuracy of predictions has diminished the interpretability of many models—leaving users with little understanding of the model’s behavior or trust in its predictions. The field of eXplainable artificial intelli...Starting at €8.20

Logistic Regression: Modeling with StatTools
Lichtendahl, Kenneth C. Jr.; Andrasko, Joe; Boatright, BenjaminTechnical Note DARDEN-QA-0945-EDecision AnalysisLogistic regression is a modeling technique often used to predict a binary variable—a variable coded as 1 if an event of interest occurs (e.g., a borrower defaults on a loan) and coded as 0 otherwise. This note details how logistic regression applies the logistic function to generate a probability forecast for a binary event. It also includes an example of how to fit a logistic regression model to loan default data using StatTools (an Excel add-i...Starting at €8.20
