No, this is not quite right: which.max
-- Jonathan Baron, Professor of Psychology, University of Pennsylvania Home page: http://www.sas.upenn.edu/~baron R search page: http://finzi.psych.upenn.edu/ You need to be more careful 1. For a continuous distribution, the mode is ** not ** the most frequent value (this has no meaning) -- it is the maximum of the density function. So you must fit a density function and then estimate the mode, perhaps by using which.max() on a discretization of the fitted density. Or, if you have the fitted density in closed form (and it is unimodal) you can use calculus. 2. For a discrete distribution, which could be the sample empirical distribution,use which.max(table()). -- Bert Gunter ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
