Re: [R] question from environmental statistics
Dear Dev
I believe you may need some conceptual guidance in probability theory and
statistics rather than help with a specific R function to solve your
analysis. May I recomend you to visit the statistic consulting office in
your campus or perhaps review a textbook on applied probability.
Best wishes

thanks Fran. that was useful but Im still in a fix. its a real life data
which
looks like this:
0.9
10.9
24.0
6.7
0.6
1.0
2.4
12.4
7.9
15.8
1.4
7.9
11000.0
(benzene conc. taken after WTC attacks)..its just a small chunk of data i
pasted
for you to look at.
its neither normal nor lognormal. someone told me that qq plot does help in
determining the distribution. im not sure how to get it.
can someone help me in this.
thanks
Take a look at this document by Vito Ricci:
http://cran.r-project.org/doc/contrib/Ricci-distributions-en.pdf
Did you try RSiteSearch(Fit distribution) or a Google search? That will
lead you to fit.dist{gnlm} and fitdistr{MASS}

Dear R users
I want to knw if there is a way in which a raw dataset can be modelled by
some
distribution. besides the gof test is there any test involving gamma or
lognormal that would fit the data.
thank you
