This dataset contains interval data of car specifications, including min-max values. It is composed of 5 variables: Engine Capacity, Top Speed, Acceleration, Price and Class. The aggregation of the microdata was done by car model.
Usage
data(intCars)Format
A list with the following components:
microdataA data frame with
27rows and9columns. It contains the lower and upper bounds for each variable.intDataAn
intDataobject with27interval-valued observations and4variables. The variable "Price" was log-transformed into "lnPrice". The microdata are not available, thus the default parameters of the latent distributions were used assuming a uniform distribution.
