...en trying to figure out how to use the nonlinear regression to fit the cumulative lognormal distribution to a number of data points I have but I am a new R user and I cant quite decipher the notes on nonlinear regression. Any help in this regard will be greatly appreciated, my email address is mmiller at nassp.uct.ac.za

Recently, I have been working with some data that look like two overlapping gaussian distributions. I would like to either 1) determine the mean and SD for each of the two distributions OR 2) get some (bayesian ?) statistic that estimates how likely an observation is to belong to the left-hand or right-hand distribution In case I'm using the wrong language, my data looks something like

When using fitdistr() with the exponential, log-normal and beta distributions, you get the relevent rate, mean, standard deviation, shape1 and shape2 but you get a number bellow those that are in () and I was wandering what exactly those numbers represent and how they relate to the data.

...r's book. It didn't work; the group is not seen by the NT Server when setting the share permissions. Is this support available in the latest and greatest (2.05a)? Will it be available soon? Is there a work around? Any help will be greatly appreciated. Matt Miller Systems Administrator mmiller@vermeermfg.com

I am using the MASS library function fitdistr(x, dpois, list(lambda=2)) but I get Error in optim(start, mylogfn, x = x, hessian = TRUE, ...) : Function cannot be evaluated at initial parameters In addition: There were 50 or more warnings (use warnings() to see the first 50) and all the first 50 warnings say 1: non-integer x = 1.452222 etc Can anyone tell me what I am doing

Can someone show me how to set up DUNDi, I will be using it to connect 14 asterisk servers internally. I don't want to use it on the external world. If anyone has any examples of connecting 2 or 3 (if their is a difference) machines in a DUNDi co-operation that would be helpful. Johnathan Falk Network Administrator Clinton Community Schools

I would like to know how I can change the axis to run from 0 to 50 say, instead of the 0 to 200 it gives me. Many thanks Mark Miller

Has anyone attempted to change the MeetMe enter and exit sounds. I see that the raw values in the enter.h and exit.h files. If I want to change the sounds is it as easy as converting the auto files to .raw and place the text in the file? I don't believe there is a header in the raw format. Thanks Michael
