| Feb 18, 2015 at 16:25 | comment | added | Arek | I'm writing my Master Thesis at the University about Extreme Wind Speed in Poland. I have a kind of data like I wrote above and I would like to analyse my data by means of Weibul distribution (You know, I want to find the percentiles [0,9; 0,95; 0,999] by menas of qweibull() and I need to do this the paramets of Weibull distribuation). I'm not to good with statistic and I need some help. | |

Since you have plenty of data, I'd suggest bins equal to the discrete intervals your data are already binned to. 2. Your data show a heavier right tail than the Weibull that would describe the middle part of the data, and a heavier left tail as well. 3. If your data were close to a Weibull ... what you would do? | |
