We examine the determinants of voluntary adoption of IFRS by medium-to-large UK unlisted firms (8417 firms comprising 287 IFRS firms and 8130 non-IFRS firms in 2009). Analysing voluntary adoption allows us to better understand the cost/benefits of choosing a specific set of accounting standards. Using univariate and multivariate analyses, we find that internationality, leverage, firm size and a...

An analysis of birth weight was undertaken on secondary data derived from the Malaysian Family Life Survey II. A total of 1629 last singleton live birth infants was analysed with the aim of identifying from the variables available potential risk factors for low birth weight. Univariate and subsequently multivariate analyses were carried out for this purpose. The incidence of low birth weight wa...

PURPOSE The purpose of this study was to examine whether childhood misfortune reduces the likelihood of being disease free in adulthood. DESIGN AND METHODS This article used a sample of 3,000+ American adults, aged 25-74, who were first interviewed in 1995 and reinterviewed in 2005. Logistic regression was used to estimate the odds of avoiding disease at the first wave and remaining disease f...

Multivariate longitudinal ordinal data are often involved in studies with each individual having more than one measure. However, due to complicated correlation structures within and no explicit likelihood functions, analyzing multivariate is quite challenging. In this paper, Markov chain Monte Carlo (MCMC) sampling methods developed analyze by extending probit (MVP) models for univariate multip...

A new approach for monitoring the state of conservation of cultural heritage objects surfaces is being developed. The technique utilizes multi-spectral imaging, multivariate analysis and statistical process control theory for the automatic detection of a possible deterioration process, its localization and identification, and the wavelengths most sensitive to detecting this before the human eye...

OBJECTIVES We compared health status, access to care, and utilization of medical services in the United States and Canada and compared disparities according to race, income, and immigrant status. METHODS We analyzed population-based data on 3505 Canadian and 5183 US adults from the Joint Canada/US Survey of Health. Controlling for gender, age, income, race, and immigrant status, we used logis...

BACKGROUND Caesarean section birth is a frequent mode of delivery worldwide. Several social factors have been demonstrated to be strong predictors of caesarean births. OBJECTIVES To identify possible social predictors of caesarean section births in Italy. METHODS Data for this study were drawn from the Italian Institute of Statistics (ISTAT) survey conducted during year 2005 which comprised...

We investigated seven distance measures in a set of observations of physicochemical variables of mango (Mangifera indica) submitted to multivariate analyses (distance, projection and grouping). To estimate the distance measurements, five mango progeny (total of 25 genotypes) were analyzed, using six fruit physicochemical descriptors (fruit weight, equatorial diameter, longitudinal diamete...

BACKGROUND AND AIMS Specific leaf area (SLA), a key element of the 'worldwide leaf economics spectrum', is the preferred 'soft' plant trait for assessing soil fertility. SLA is a function of leaf dry matter content (LDMC) and leaf thickness (LT). The first, LDMC, defines leaf construction costs and can be used instead of SLA. However, LT identifies shade at its lowest extreme and succulence at ...

There has been considerable recent interest in factor-analytic models for the analysis of genotype by environment type problems. It is shown that, compared to ‘standard’ multivariate analyses, such models can substantially reduce computational requirements for international genetic evaluation of beef cattle, fitting an animal model and treating performance in different countries as separate tra...
