I have 10 years worth of mean wind speed meteorological data (timely 10-minutes data). I want to compare the observed wind speed data against a Weibull distribution on a graph of the probability density distribution. I used function in R:fitdistr(). But the Weibull paramets, which gave me this function is probably wrong? Because when I made qqPlot with this paramets, I had something like this:
Help me please and tell me, what I have been wrong? What should I do?
