The Combination Confidence Region Of The Two Parameters In The Popular Distributions And The Exploration Of The Best Combination Confidence Region

The interval estimation is an important method to estimate the unknown parameters for popular distribution and it is useful for guiding practical production. In this paper,based on the definition of the confidence interval,we obtaine the combination confidence region of the two parameters for popular distributions. And ,the best combination confidence region of the two parameters are discussed. Standard normal distribution N(0,1) is taken as an example to verify the availabity of the mothed.
