The Power-Normal Distribution: Application to forest
... There is a slight tendency that SB underestimates the mean of the distribution (by about 0.5 %), and in some lesser degree, PN overestimates the mean with about 0.5 %. See Figure 5. But for most cases, both estimated distributions have a mean very close to the true mean. (The means of the estimat ...

Some parts are then randomly selected, and then all the members of the chosen parts are picked as sample elements. In this design a cluster is drawn randomly and all its members become sampl ...

8. Convergence in Distribution
... Suppose that f n , n ∈ ℕ+ and f are probability density functions for discrete distributions on a countable set S, and that f n ( x) → f ( x) as n → ∞ for each x ∈ S. Then the distribution defined by f n converges to the distribution defined by f as n → ∞. Similarly, suppose that f n , n ∈ ℕ+ and f ...
