carcustomers {extracat} | R Documentation |
This dataset is taken from the website of the Department of Statistics, University of Munich.
The data are based upon a poll from a german car-company. In 1983 questionnaires were sent to 2000 customers, who had purchased a new car approximately three months earlier. The point of interest was the degree of satisfaction, reasons for the particular choice, consumer profile, etc. Participation was of course voluntary. Only 1182 persons answered the questions and after removing forms with "missing values" only 793 questionnnaires remained. Each form contained 46 questions, which resulted in a dataset of 46 covariates with 793 observations each. Due to the abundance of ordinal and categorical covariates the dataset is particularly suited for generalized linear models.
