The e-book, belonging to the sequence “Studies in Theoretical and utilized statistics– chosen Papers from the Statistical Societies”, offers a peer-reviewed number of contributions on appropriate themes equipped through the editors at the get together of the SIS 2013 Statistical convention "Advances in Latent Variables. equipment, versions and Applications", held on the division of Economics and administration of the college of Brescia from June 19 to 21, 2013.
The concentration of the e-book is on advances in statistical tools for analyses with latent variables. actually, lately, there was expanding curiosity during this huge examine quarter from either a theoretical and an utilized standpoint, because the statistical latent variable process permits the powerful modeling of advanced real-life phenomena in quite a lot of study fields.
A significant objective of the quantity is to collect articles written by way of statisticians from varied examine fields, which current diversified ways and studies concerning the research of unobservable variables and the examine of the relationships among them.

This booklet constitutes the completely refereed post-proceedings of the 4th overseas convention on Parallel Processing and utilized arithmetic, PPAM 2002, held in Naleczow, Poland, in September 2001. The one zero one papers offered have been conscientiously reviewed and better in the course of rounds of reviewing and revision.
The e-book questions key dichotomies: that of the plain and genuine, and that of the interior and exterior.

Our international is skilled as chances of motion, and to understand is to grasp what to do. yet another outcome is that the brain is healthier regarded as a estate of organisms’ interactions with their setting.
This booklet examines the bottom-up applicability of swarm intelligence to fixing a number of difficulties, corresponding to curve becoming, picture segmentation, and swarm robotics. It compares the services of a few of the better-known bio-inspired optimization techniques, in particular Particle Swarm Optimization (PSO), Darwinian Particle Swarm Optimization (DPSO) and the lately proposed Fractional Order Darwinian Particle Swarm Optimization (FODPSO), and comprehensively discusses their merits and downsides.

Further, one of the main arguments in favour of considering the Octavia a not original tragedy of Seneca is that one of the characters of the story is named Seneca, which is again reflected by our principal component analysis.
In this article the Plackett distribution is used in order to construct a bivariate distribution from CUB margins. Furthermore, the model is extended so that the effect of rater characteristics on their stated preferences is included. Keywords CUB models • Food quality • Ordinal data • Plackett distribution 1 Introduction The level of consumer satisfaction with products and services is often investigated by complex surveys. In such a context, respondents may be requested to rate several attributes and to express their preferences by means of a Likert scale.
