The results from both the Mycielski-3 and K-means clustering are shown in Table16. In terms of graphical analysis, the results for prediction are interpreted as shown in Fig. 8. From the figure, the plot of the line graph for K-means clustering describes quite well the wind speed for Kudat in 2010. The red line shows the highest frequency at 6 m s_1. However, it over-predicted the majority of the site's wind speed. Meanwhile, the graph of the Mycielski-3 prediction was over-predicted at 8 ms_1. Conversely, Weibull estimation by using the low percentile tended to be lower fre- quencies of the majority wind speed. The frequency in the analysis indicated the number of times that the wind blew at such a speed.
