The left chart plots epsilon in mean of theta percent against theta over L with values 0.025, 0.05, 0.1, and 0.25. Three lines for C O V x 10 percent, 20 percent, and 30 percent all increase, reaching about 24 to 25 percent at 0.25. The right chart shows sigma of theta percent versus theta over L with the same x values. All three lines rise steadily from about 0.14 to about 1.45, with minimal difference between C O V x cases.
The effect of for case 1, (, is varying and L is kept constant (L = 20)) on (a) in mean of and (b) in mean of
