WebA sampling distribution is the probability distribution of a given statistic, such as the mean. To illustrate a sampling distribution, let's examine a simple example where the complete … WebMay 29, 2014 · The sampling distribution of S 2 is σ 2 n − 1 χ n − 1 2. The mean of a χ n − 1 2 random variable is n − 1. The variance of a χ n − 1 2 random variable is 2 ( n − 1). You are not required to prove these results.) (iv) Use these results to show that S 2 is an unbiased estimator of σ 2 and that its variance is 2 σ 4 n − 1.

Characteristics of Estimators
WebAn estimator is unbiased if, on average, it hits the true parameter value. That is, the mean of the sampling distribution of the estimator is equal to the true parameter value. The two … WebThis paper discusses the sequential estimation of the scale parameter of the Rayleigh distribution using the three-stage sequential sampling procedure proposed by Hall (Ann. Stat.1981, 9, 1229–1238). Both point and confidence interval estimation are considered via a unified optimal decision framework, which enables one to make the … WebOct 1, 2024 · 01 Oct 2024 A point estimator (PE) is a sample statistic used to estimate an unknown population parameter. It is a random variable and therefore varies from sample to sample. A good example of an estimator is the sample mean x, which helps statisticians estimate the population mean, μ. triangular merger explained
