1. 36. Maximum spacing methods and limit theorems for statistics based on spacings

   Författare :Magnus Ekström; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Estimation; spacings; maximum spacing method; consistency; ^-divergence; goodness of fit; unimodal density; entropy estimation; uniform distribution;

   Sammanfattning : The maximum spacing (MSP) method, introduced by Cheng and Amin (1983) and independently by Ranneby (1984), is a general estimation method for continuous univariate distributions. The MSP method, which is closely related to the maximum likelihood (ML) method, can be derived from an approximation based on simple spacings of the Kullback-Leibler information. LÄS MER

   Sammanfattning : The mobile industry is preparing to scale up the network capacity by a factor of 1000x in order to cope with the staggering growth in mobile traffic. As a consequence, there is a tremendous pressure on the network infrastructure, where more cost-effective, flexible, high speed connectivity solutions are being sought for. LÄS MER
