The most critical thing during the site choice for offshore wind farm development is wind<br />

climate analysis. For this case, accurate wind data are needed. Buoy measurement is<br />

considered as a reference source of data obtained from less accurate sources. The<br />

regression techniques developed by using the principle of ordinary least squares (OLS).<br />

But wind speed data normally containing several outliers that cause the validity of the<br />

regression analysis may be questioned if it is not accurately checked. This research<br />

concentrated on the implementation of the most important robust regression method,<br />

which can detect and reveal outliers and maintain their efficiency at the same time. The<br />

data used for this research is taken from National Data Buoy Center. The used of robust<br />

regression is vital in wind speed application as outliers are present in the available data<br />

sample. The estimators used in this study are S-estimator, LTS-estimator, M-estimator,<br />

and MM-estimator.<br />
