Mle of double exponential distribution
WebGiven a sample of size nfrom a two-parameter exponential distribution, we are interested in estimating both and . The most widely used method to do estimation is Maximum Likelihood Estimation(MLE). Under some regularity conditions, the MLE method has nice properties such as consistency and e ciency. The regular MLE is Web29 aug. 2024 · I am trying to fit a double-exponential (i.e. mixture of two exponential or bi-exp) data using MLE. Though there is no direct example of such a problem, yet I found …

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… WebThe two-parameter exponential distribution has many applications in real life. In this project we consider estimation problem of the two unknown parameters. The most widely …
