Abstract
This study aimed to estimate the parameter scale è and the shape parameter ë
of the Weibull distribution and to compare the estimation methods (Maximum
likelihood, Moments, least squares and maximum loss of Minimax) by the
mean square error to obtain the best estimate. Actual data for the monthly
wind velocity of sebha city -Libya were used for 52 years. The value of
median, third quartile, eighty-fifth percentile and the maximum value in each
year as measurements and variables of the study. the statistical package
program R was used in the application. The results showed that the best
method of estimation was the maximum loss method Minimax, then the
maximum likelihood then moments then lestsquares method. The study also
recommended that make comparisons between traditional methods of
Minimum Variance bound and the highest exponential loss function and the reliance on the eighty-fifth percentile scale in the calculation of wind speed.
