Recommendations are welcome on published methods to address the following type of question:
A fixed set of athletes 1:N participate to 1:p distinct competitions. From the full N times p matrix of results (e.g. Arrival times, scores,…) an equivalent size matrix of ranks is calculated.Column 1:p of this rank matrix lists a 1 for first classified and so forth up to N for the last athlete for each competition.A sports commentator wishes to cluster this matrix so as to discriminate groups of athletes associated to a distinctive pattern of results.For instance, some athletes may be more versed for endurance competitions and less so for short-distance fast competitions.A priori, the number and nature of these patterns are unknown.
Best wishes
