Re: st: spearman rank correlation

[jean-luc morin-chesnel <jeanluc.morinchesnel@gmail.com>]

thanks mr cox for your kind answer.

well I would like to know whether past successes lead on average to futures ones
so maybe one way would be to -reg future_score past_score, vce(cluster id)
but is seems that using a spearman rank correlation is a more robust
way to go (I guess)

thanks again
