In many medical journals, reviewers only want to see some error bars. In 90% of the cases, these are wrong or misleading, but it is hopeless to argue with medical professors playing statisticians. So I give them the square-root of the counts, which is not much worse than anything else, but I do not claim these to be confidence intervals. Have some good excuse ready when some counts are low. If you are working in a more serious field, you might consider giving something like estimates of the parameters, but you cannot plot these in your curves easily. Try fitdistr in package MASS for a starter. > > > > You must know your password to change your options (including changing > > the password, itself) or to unsubscribe.
