WebFisher information tells us how much information about an unknown parameter we can get from a sample. In other words, it tells us how well we can measure a parameter, … WebIt is known that the Fisher information in any set of order statistics can be simplified to a sum of double integrals. In this article, we show that it can be further simplified to a sum of single integrals for the scale parameter of an exponential distribution. Moreover, we use the result and provide a simple method of obtaining the optimal ...
