A data frame with 500 observations on the following 2 variables.
Y1
first numeric contaminated variable
Y2
second numeric contaminated variable
Details
Data have been simulated by Gaussian contamination model with two
contaminated variables (Y1,Y2) with parameters
B=(1.03, 0.96), sigma=matrix(c(1.22, 1.42,1.42, 2.89),2,2), w=0.05, lambda=10.
