Discrete choice research: a guide to experimental design, model specification, and model estimation with R scripts
Decision research has applications in a wide range of fields from marketing to healthcare to environmental science all over the world. For example, it is required as part of feasibility studies for public transport investments if they are co-financed by the European Union. The publication presents an introduction to applied decision-making research using the experimental method of expressed preferences and discrete choice analysis, focusing especially on the use of these methods in transport. The introduction briefly covers the history of decision-making research and some methodological assumptions of this research. It also presents the basic decision-making model, the design of the expressed preferences experiment, and the subsequent data analysis. On two examples, it shows the practical use of the method of expressed preferences and discrete choice analysis, it shows the creation of the design of the experiment and the analysis of the results in practice, including the interpretation of the results. The book works with the author's freely accessible datasets and with scripts written for the statistical tool R. After reading the book, the reader will be able to prepare a simple research on expressed preferences, analyze it using basic models of discrete choices and interpret the basic results.
