Using 2-dimensional MDS with 6 to 100 points and ten levels of error, it is found that adding more points (given that n>10) is driving up the Stress of the MDS solutions but also leads to better recovery, in general. The recovery exceeds any reasonable statistical benchmarks, i.e. more points enable MDS to smooth out the error in the data so that the true configuration can surface more clearly in the MDS solution.</p>}, number={2}, journal={Austrian Journal of Statistics}, author={Borg, Ingwer}, year={2020}, month={Feb.}, pages={43–52} }
