The main purpose of statistical inference is 1. to estimate the parameters(the quantities that represent a particular characteristic of a population) on the basis of sample observations through a statistic ( a function of sample values which does not involve any parameter). (Theory of Estimation). 2. to compare these parameters among themselves on the basis of observations and their estimates (...

In animal breeding, knowledge of the genetic properties of the traits we are interested in is the first prerequisite in establishing a selection programme. Unless we are concerned with traits controlled by single or few genes, in which case we are generally more interested in gene frequencies, estimation of genetic parameters is synonymous with the estimation of variance components. In this con...

We identified cases where the Jolly-Seber estimator of population size is biased under tag loss and tag-induced mortality by examining the mathematical arguments and performing computer simulations. We found that, except under certain tag-loss models and high sample sizes, the population size estimators (uncorrected for tag loss) are severely biased high when tag loss or tag-induced mortality o...

This paper presents our research work of estimating articulatory states and model parameters from speech acoustics. This work represents a prerequisite for a speech recognition system based on articulatory dynamical models. The model parameter estimation was based on the vowels obtained from 590 sentences of 59 speakers from TIMIT speech database, whereas the state estimation experiments have b...

if we try to estimate the parameters of the ar process {xn} using the observed process {xn+zn} then these estimates will be badly biased and not consistent but we can minimize the damage using a robust estimation procedure such as gm-estimation. the question is does additive contamination affect estimates of “core” parameters in the infinite variance case to the same extent that it does in the ...

With this paper, we present a collaborative environment called the WebDesk, that attempts to create a single homogeneous and integrated framework for distributed collaboration. The WebDesk is part of the Esprit 20598 MATES project, which is supported by the Information Technology part of the 4:th Framework Program of the European Union. We believe that the WebDesk will be a forerunner in utiliz...

Nous donnons une preuve de la NP-complétude de SAT en se basant sur une caractérisation logique de la classe NP donnée par Fagin en 1974. Ensuite, nous illustrons une partie de la preuve en montrant comment deux problèmes bien connus, le problème de MAX STABLE et de 3-COLORATION peuvent s’exprimer sous forme conjonctive normale. Enfin, dans le même esprit, nous redémontrons la min NPOcomplétude...

The DISC project aims to (a) build an in-depth understanding of the state-of-the-art in spoken language dialogue systems (SLDSs) and components development and evaluation with the purpose of (b) developing a first best practice methodology in the field. The methodology will be accompanied by (c) a series of development and evaluation support tools. To the limited extent possible within the dura...

| In this paper, we report on the integration of informal, semiformal and formal system speciication techniques. We present a framework for system speciication called TRADE, within which several well-known semiformal speciication techniques are placed. TRADE is based on an analysis of structured and object-oriented requirements speciication methods. In this paper, we combine TRADE with the logi...
