I have got a set of wind speed data of every months.

An example would be great!

Thank you!

The second issue seems to be about actually do the estimation for the actual data. I guess that there are available software in R.

(By the way, Weibull was a person. I spell it with "W")

I have already finished reading dozens of research papers on Weibull parameters estimation using different methods and I am familiar with several methods to calculate Weibull parameters. After some literature reviews, I have almost finished making outlines for my paper but I still have one last query which is very important for evaluation.

I am having problem with calculating "predicted values" of wind speed with respect to Weibull distribution.

As you know RMSE requires "predicted values" and "observed values" for its calculation, I am not finding the way to calculate "predicted values" anywhere.

After calculating k and c for all methods I mentioned, I need to have "predicted values" for every methods so that I could calculate RMSE for each methods and compare finally.

Thank you!
