Sampling of length and age distributions of catches is important for the assessment of commercially fished stocks. This paper presents a new method for statistical analyses and comparisons of length and age distributions based on generalised linear models of continuation-ratio logits. The method allows statistical testing of the effects of both continuous and discrete variables. Further, by utilising the smoothness of length and age distributions as a function of length, the method provides more accurate estimates of these distributions than traditional methods. The observations are assumed to be multinomially distributed, but cases in which the variance exceeds that of this distribution may also be analysed. The implementation of the method in existing statistical analysis software is straightforward and is demonstrated using length and age distributions of the lesser sandeel, Ammodytes marinus Raitt.

Select 45 pieces of silk, cotton and wool fabrics in total, with semi-circular skirt modeling as object of study, investigate the relationship between flare sagging in straight & inclined grains of skirt pieces and fabric types, analyze the influence of hem parameters on flare sagging of semi-circular skirt and obtain multiple linear regression equation by disposing the measured data with SPSS statistical analysis software. The study result shows that the skirt hem of silk fabric is sagging more significantly than that of cotton and wool fabrics and there is a multi-linear relationship between semi-circular flare sagging and parameters.The research of this subject has both theoretical value and practical value.

Abstract Although some researchers report the normative production of the rhotics in Traditional New Mexico Spanish, others have reported variability, including the presence of an English-like vocalized rhotic. In the present study, 29 speakers of Spanish from Taos, a city in northern New Mexico, were interviewed and the rhotics of their speech were categorized, quantified and analyzed using speech analysis and multivariate statistical analysis software. The results show variation and change when compared to previous reports (both recent and of over a century ago). In spontaneous and elicited speech, ten distinct rhotic variants, subsequently recoded into five categories, were observed and quantified. Moreover, approximant and assibilated variants have notable frequencies and conditioning factors. VARBRUL analyses reveal phonological context, stress, word position, age, and sex as significant conditioning factors.

The limited literature on the pedigrees of tiqueurs, including those with Gilles de la Tourette's syndrome, is reviewed. Most statistical analyses have been restricted to affected family members without specifying the unaffected ones. The present statistical analysis of a series of child tiqueurs, including 91 probands and 1293 first- and second-degree relatives, 46 of whom were tiqueurs, predicts the odds on being a tiqueur for individuals, and establishes how those odds are affected by certain explanatory variables using log-linear models. The data do not confirm a familial pattern beyond reasonable doubt, but if the suggested prevalence of tics in the population is 10% then the figure for parents is large enough to support a familial hypothesis. The pedigrees do not indicate a simple mode of genetic transmission. Further research is needed to confirm that there is a connection between childhood tics and Gilles de la Tourette's syndrome, to establish that the predisposition to tics is familial, and, if so, whether there is a complex genetic mechanism involved, or some other environmental aetiology so far undisclosed.

Resumo Contexto Os dispositivos de oclusão vascular (DOV) permitem rápida remoção da bainha introdutora de um acesso arterial, reduzindo o tempo de hemostasia, a restrição do paciente ao leito e as complicações no sítio de punção. Objetivos Avaliar a eficácia e possíveis complicações do uso de dispositivo de oclusão arterial comparado com a compressão manual. Métodos Estudo longitudinal prospectivo randomizado com 20 pacientes no período de dezembro de 2014 a julho de 2015 em Maringá (PR). Foram divididos em dois grupos: aqueles que utilizaram DOV (grupo DOV) e aqueles submetido apenas a compressão manual (grupo CM). Realizaram-se exames de ultrassom Doppler para avaliar a espessura pele-artéria pré e pós-procedimento e verificou-se o tempo de compressão e de deambulação. Os dados foram analisados pelo Programa Statistical Analysis Software. Resultados Um total de 60% dos pacientes eram do sexo masculino e a média de idade de ambos os grupos foi de aproximadamente 60 anos. Não houve diferença na espessura pele-artéria entre os grupos. O tempo de compressão no grupo DOV foi de 2 minutos e no grupo CM foi de 21±2,11 minutos (p = 0,0005), e o tempo para retorno de movimentos no membro inferior puncionado foi de 2,35±0,75 horas no grupo DOV e de 6 horas no grupo CM (p = 0,0005). Não houve complicações. Conclusões Neste estudo a hemostasia por compressão manual foi tão efetiva quanto o uso de DOV, embora o tempo de compressão e o tempo para retorno às atividades sejam menores nos pacientes submetidos ao uso do dispositivo.

The research was done for a high school competition where teams were given a data set of grocery store transactions and asked to pull interesting information out of the data. Our approach was to determine whether the approximate distance between the customer's home and the store had any impact on their spending, the hypothesis being that the greater the distance, the more the customer would spend over an extended period of time (three years). The reasoning behind this was that customers who travelled greater distances to reach a specific store would likely be motivated to buy more in order to justify the greater journey. The primary tools we used to test our hypothesis were Statistical Analysis Software (SAS) and Microsoft Excel. Our results obtained contradicted the initial hypothesis; it was found that shoppers who live closer to the stores spend much more than those who live further away.

Chinese traditional shadow play has been selected into the List of Intangible Cultural Heritage in 2011. Yet, reflecting abundant national cultural values, such traditional art form is degenerating and fading out from people’s sight. As the earliest statistical analysis software, Statistical Package for the Social Science (SPSS) is comprehensive in analyzing and managing statistical data. This study explores the application of SPSS in minimizing the workload of researchers while raising the validity of data in supporting the analysis of the survey data which reflected the inheritance and development of Chinese traditional shadow play in schools.
