Not in general, and probably not any more practically useful than F^(-1)(0.5). > the reason for asking is since the median of the particular distribution > that i am interested in is difficult (probably impossible) to obtain. > the median depends depends on an incomplete gamma distribution. the > moments however can be obtained fairly easily. R can calculate the incomplete gamma function (see ?pgamma), so that's not necessarily a stumbling block.
