A Cross-Section Analysis of Non-Business Air Travel
Abstract For any individual adult what linear combination of variables yields the best estimate of the probability that he will take at least one non-business air trip in a year? Given that an individual will take at least one non-business air trip, what variables yield the best estimate of the number of such trips which he will take? This paper is a report of an attempt to answer these questions through multiple regressions based on data from a survey covering a cross-section of the adult population of the United States. Most of the analysis is devoted to the question of what factors determine the probability that an individual will take at least one air trip. * The analysis reported here has been carried out as a project of the Research Seminar in Quantitative Economics of the Department of Economics of the University of Michigan. The data were made available to the Research Seminar by the Survey Research Center, a unit of the Institute for Social Research of the University. The authors are indebted to ...
