Parameter Estimation for Type III Discrete Weibull Distribution: A Comparative Study

Figure 3

Boxplot of Monte Carlo distributions of 𝑐̂ and 𝛽 for three parameter combinations (𝑛=50 and 5,000 MC runs). The dashed horizontal lines indicate the true value of the parameters 𝑐 and 𝛽.

(a) 𝑐(̂𝑐=0.1,𝛽=0.75)

(b) 𝛽(𝑐=0.1,𝛽=0.75)

(c) 𝑐(̂𝑐=0.4,𝛽=0.25)

(d) 𝛽(𝑐=0.4,𝛽=0.25)

(e) 𝑐(̂𝑐=0.8,𝛽=−0.25)

(f) 𝛽(𝑐=0.8,𝛽=−0.25)
