Necessary Sample Size for Estimating the Scale Parameter With Specified Closeness and Confidence
摘要
In this paper, we discuss how to determine the optimum sample size by pre-specified confidence interval for estimating the scale parameter from a family of skew normal distributions. We also obtain its specified confidence interval. Subsequently, we extend the mathematics to apply to two independent samples from normal distributions and feature the scale ratio in the process. Finally, simulation work and real data application support our main results.
