  Computing such correlation coefficient would be straightforward had we had
available the rankings given by the prize committee to all scientists in the
pool. In reality we only have citation rankings for all scientists. This means,
however, that we have the ordinal rankings of the prize winners with regard to
citation metrics. I use maximum likelihood method to infer the most probable
correlation coefficient to produce the observed pattern of ordinal ranks of the
prize winners. I get the correlation coefficients of 0.47 and 0.59 between the
composite citation indicator and getting Abel Prize and Fields Medal,
respectively. The correlation coefficient between getting a Nobel Prize and the
Q-factor is 0.65. These coefficients are of the same magnitude as the
correlation coefficient between Elo ratings of the chess players and their
popularity measured as numbers of webpages mentioning the players.
