The list moderator has pointed out that there is currently no mechanism to attach files to messages to this list. If anyone is interested in receiving the Hugin network file which illustrates our problem of moving from point estimates to probability distributions I will gladly send it to these persons directly. (Thanks go out to the 3-4 list members how have already expressed an interest and requested the file - I look forward to your insights).
