Which of the following is not a way to assess reliability and validity of the MDS solution?
A)Collect input data at two different points in time and then determine test-retest reliability.
B)Selectively eliminate stimuli from the input data and then determine the solution from the remaining stimuli.
C)Add a random error term to the input data,subject the resulting data to MDS analysis,and compare the solutions.
D)All of the above are ways to assess reliability and validity.

All the options listed (A, B, and C) are indeed methods to assess the reliability and validity of a Multidimensional Scaling (MDS) solution. Collecting data at different times (A) assesses stability over time, selectively eliminating stimuli (B) checks for consistency, and adding a random error term (C) evaluates the robustness of the solution against noise.
