Hi,
I understand that you have collected 30 parameters for 200 states and you want to generate an index from them using CKYL method which should use pairwise comparisons.
While MATLAB does not have built-in functions specifically for the Condorcet-Kemeny-Young-Levenglick (CKYL) method or other specific aggregation methods you mentioned, you can implement these methods using MATLAB's capabilities for pairwise comparisons and matrix operations:
1. Create a matrix that represents the pairwise comparisons between your parameters. Each element of the matrix represents the preference or ranking of one parameter over another. You can define the values based on your specific requirements and preferences.
2. Perform calculations on the pairwise comparison matrix to obtain scores for each parameter. The CKYL method, for example, involves counting the number of times each parameter is ranked first in the pairwise comparisons.
3. Use the scores obtained from the pairwise comparisons to aggregate and rank the parameters. Each method may have its own specific aggregation formula or algorithm.
Here is the code example for your reference:
pairwiseMatrix = [0, 2, 3; 1, 0, 1; 0, 1, 0];
scores = sum(pairwiseMatrix == 0, 2);
[~, ranking] = sort(scores, 'descend');
disp(ranking);
