This dataset results of a simulation on the basis of Sierpinski-Carpet with a [p,p,p,q]-model with fixed values of p = 0.5 and q = 0.1. Data was simulated in JAVA and every cell of data is filled with either zeros or ones. It is a simulation example for breast mammography screenings where the result is a black and white picture and values zero and ones stand for black and white.
data(Data0501)
A data frame with 81 observations on the following 81 variables. These 81 variables result from 3^4, which means fourth ramification of Sierpinski-Carpet.
