Choice-based samples: A nonparametric approach.
01 January 1986
Choice based sampling refers to a sampling situation, often occurring in market research experiments, where it is necessary to stratify the population according to the choices individuals make and then sample from the different strata. This dependency between the individuals' choices and the sample selection probability introduces sampling bias, and various methods ranging from fully parametric to semiparametric have been proposed. This conditional probability of choice given attributes is of major interest in studies where a primary goal is assessing product acceptance within a segment of the population.
