Web3 Answers Sorted by: 1 The asymptotic confidence interval may be based on the (asymptotic) distribution of the mle. The Fisher information for this problem is given by . Hence an asymptotic CI for is given by where we have replaced by its mle, since we do not know the population parameter. In probability theory and statistics, the Laplace distribution is a continuous probability distribution named after Pierre-Simon Laplace. It is also sometimes called the double exponential distribution, because it can be thought of as two exponential distributions (with an additional location parameter) spliced together along the abscissa, although the term is also sometimes used to refer to the G… ezetrol adelgaza
