This simulated data set are discussed by McLachlan and Peel (2000). The data consists of 100 observations generated from a 3-component bivariate normal mixture model with equal mixing proportions. Fifty outliers, generated from a uniform distribution over the range -10 to 10 on each variate are added to the original data. Thus a sample of 150 observations is obtained.
A data frame with 100 observations on the following 3 variables.
a numeric vector of x-coordinates
a numeric vector of y-coordinates
a numeric vector of cluster memberships
