Print on Demand. This book investigates essential factors for accurately estimating the parameters of zero order models frequently used to represent brand switching behavior. Combining insights from previous research and mathematical modeling, it explores the sensitivity of maximum likelihood estimates, providing valuable guidance on sample size requirements for parameter estimation with a specific accuracy level. The book further explores the implications of sample size and purchase sequence length and highlights how, in many applications, knowledge of the transformed parameters, such as market share and loyalty index, can be sufficient. By providing practical insights and quantitative analysis, this book offers a valuable tool for researchers and practitioners seeking to improve the accuracy and efficiency of their zero order models. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. …

Shoemaker and Staelin [ll] examined the effects of sampling variation on market share estimates of new consumer products in the Parfitt and Collins model Their results indicate that the coefficients of variation associated with the prediction of market shares for normally used sample sizes are in the range of 20% to Further, the sample size of over 2500 that is required for a coefficient of variation of l is much greater than that commonly used to estimate market share with the use of Parfitt and Collins model.
Van Mechelen [13] found the estimate of total buyers in a particular period in sprinter mod I [12] to be sensitive to small variations in input data. Specifically, he encountered coefficients of variation of over 20% given a small variance of 3% in the input data.
