الملخص EN

This research deals with estimating the shape parameter and the measurementparameter for the two-parameter Weibull distribution function using a linear estimationmethod to convert the distribution into a simple linear regression model and then usingthe regular least squares method (OLS) and the weighted least squares method (WLS)and compare them through the smallest mean squares error possible (MSE) In thisresearch, actual data were used to prepare the numbers of arrivals (different nationalities)to Iraq through the Zarbatiya port, and to analyze and extract the results using theMS.

Excel2007 program.

It was found that the weighted least squares method gave thebest estimator with the lowest average for the error box.

The results are obtained.
