Figure 11.
The graph shows probability density versus the coefficient of variation percent. Four curves represent theta values of 0.5 metres, 1 metre, 2 metres, and 5 metres. The peak shifts from about 61.46 percent at theta 0.5 metre to about 21.69 percent at theta 5 metre. Spread decreases as theta increases, indicating reduced variability. Each curve includes values of mean, standard deviation, and epsilon percent.Best-fitted probability density functions (pdfs) of for varying at
