The values at row X and column Y give the parameters obtained when fitting the empirical distribution of cumulated contact times between individuals of classes X and Y. The parameter m corresponds to the average of the fitted distribution, while its variance is given by m+m2/r. The numbers in parenthesis are the standard errors as given by the “fitdistr” function.
