An Examination of Tourist Arrivals Dynamics Using Short-Term Time Series Data: A Space—Time Cluster Approach

2013

The purpose of this study is to examine the development of Italian tourist areas ( circoscrizioni turistiche) through a cluster analysis of short time series. The technique is an adaptation of the functional data analysis approach developed by Abraham et al (2003), which combines spline interpolation with k-means clustering. The findings indicate the presence of two patterns (increasing and stable) averagely characterizing groups of territories. Moreover, tests of spatial contiguity suggest the presence of ‘space–time clusters’; that is, areas in the same ‘time cluster’ are also spatially contiguous. These findings appear to be more robust in particular for those series characterized by an…

Effects of Rule Changes on Game-Related Statistics in Men's Water Polo Matches

2017

The aim of this study was to investigate the effects of rule changes on game-related statistics in men's water polo matches. A total of 856 men's matches played in all Olympic Games and World Championship since 1936 was analysed. The game-related statistics considered were: total goals, winners' goals, losers' goals, goals per minute, goals difference, relationship difference goals and total goals, and relationship difference goals and winners' goals. The rule changes were grouped by structural (game and period) and functional changes (possession time, exclusion time, timing, minimum distance to take a direct shot). Differences between rule changes were determined using a one-way ANOVA. In …

Analysis of Exosomal Cargo Provides Accurate Clinical, Histologic and Mutational Information in Non-Small Cell Lung Cancer

2022

Simple Summary Non-small cell lung cancer (NSCLC) is the second most commonly diagnosed cancer and the leading cause of cancer-related death worldwide. Clinical decision-making depends on the histological classification; however, tissue biopsy is frequently not technically feasible due to tumor location or limited tissue samples. Therefore, we propose to find clinical, molecular and histological biomarkers using a minimally invasive approach based on the analysis of the cargo of the blood extracellular vesicles. Exosomes are membranous vesicles present in several biological fluids, which carry biological information to distant tissues, regulating several tumor processes. This study aims to …

The induced smoothed LASSO

2016

We propose a new lasso-type estimator of regression coefficients for regression models. Our proposal relies on the recent idea of induced smoothing and leads to estimators with sampling distribution somewhat close to the Normal one, regardless of their true value, along with the corresponding reliable covariance matrix. As a consequence inference (e.g. p-values) may be carried out relatively easily. We present results from some simulation experiments.

Il ruolo dello statistico sociale nel turismo: dalle statistiche sul turismo alle statistiche per il turismo

2008

Il presente contributo ha l’obiettivo di analizzare il ruolo dello statistico sociale nell’ambito dell’analisi dei fenomeni turistici. In particolare, lo statistico (applicato) usa e crea statistiche in funzione di obiettivi conoscitivi e operativi e, a parte l’estensione evidente delle conoscenze e degli ambiti operativi di un fenomeno come quello turistico, allo stato attuale, il contributo più urgente sul piano operativo sembra essere quello di evidenziare, ai gestori del settore, l’assenza di un adeguato livello statistico dell’informazione, nonché le distorsioni interpretative più evidenti nell’utilizzo delle statistiche esistenti. Viene inoltre illustrato come il piano conoscitivo off…

Statistica Economica con R : : laboratorio di analisi statistica di dati economici tramite software R

2018

Il volume nasce dall'esperienza didattica dell'autore nell'ambito dei corsi di Statistica Economica erogati agli studenti di Statistica all'interno dell'Ateneo di Palermo. Il testo affronta alcuni dei principali temi della Statistica Economica in un approccio applicato con un esteso utilizzo del software open source R, oggi tra i pacchetti statistici in assoluto più diffusi ed utilizzati nelle università e nel mondo del lavoro. Il volume segue un taglio laboratoriale con una presentazione e discussione di alcune tecniche, metodi ed analisi statistiche di specifica utilità per il trattamento del dato economico. Il lettore viene dunque accompagnato durante l'esposizione con continui riferimen…
