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

Francisco

**>thanks Fran. that was useful but Im still in a fix. its a real life data

**>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
