Oral health-related quality of life in native and immigrant populations in the PELFI study in Spain
(2019-05-21)
Article
Open AccessQuality of life and its relationship to oral health is an important consideration in the determinants of health of vulnerable groups. The aim of this study is to assess oral health-related quality of life (OHRQoL) and its ... -
Differences in eye health, access to eye care specialists and use of lenses among immigrant and native-Born Workers in Spain
(2019-04-01)
Article
Open AccessLatin American immigrants make up 49% of the total immigrant population in Spain, yet little is known about their eye health. The aim of this study is to determine if there are differences in self-perceived eye health, ... -
Bayesian model selection for the study of Hardy-Weinberg proportions and homogeneity of gender allele frequencies
(2019-05-29)
Article
Restricted access - publisher's policyStandard statistical tests for Hardy-Weinberg equilibrium assume the equality of allele frequencies in the sexes, whereas tests for the equality of allele frequencies in the sexes assume Hardy–Weinberg equilibrium. This ... -
Transfer function and time series outlier analysis: modelling Soil salinity in loamy sand soil by including the influences of irrigation management and soil temperature
(2017-12-13)
Article
Open AccessIn variable interval irrigation, simply including soil salinity data in the soil salinity model is not valid for making predictions, because changes in irrigation frequency must also be taken into account. This study on ... -
Which runs to skip in two-level factorial designs when not all can be performed
(2018-04-03)
Article
Restricted access - publisher's policyWhen a two-level factorial design allows estimating contrasts that can be considered negligible from scratch, it is possible to omit some runs and later estimate their values by equating to zero the expressions of some of ... -
Selecting significant effects in factorial designs: Lenth's method versus using negligible interactions
(2018-01-01)
Article
Open AccessAmong the many analytical techniques that have been published to analyze the significance of the effects in the absence of replications, two have emerged as the most widely used in text books as well as statistical software ... -
Brassica aphid (Hemiptera: Aphididae) populations are conditioned by climatic variables and parasitism level: a study case of Triângulo Mineiro, Brazil
(2017-03-20)
Article
Restricted access - publisher's policyCosmopolitan pests such as Brevicoryne brassicae, Lipaphis pseudobrassicae, and Myzus persicae (Aphididae) cause significant damage to Brassicaceae crops. Assessment of the important biotic and abiotic factors that regulate ... -
Validation and implementation of a diagnostic algorithm for DNA Detection of Bordetella pertussis, B. parapertussis, and B-holmesii in a Pediatric Referral Hospital in Barcelona, Spain
(2019-01-01)
Article
Open AccessThis study aimed to validate a comprehensive diagnostic protocolbased on real-time PCR for the rapid detection and identification ofBordetella per-tussis,Bordetella parapertussis, andBordetella holmesii, as well as its ... -
Estimating pore water electrical conductivity of sandy soil from time domain reflectometry records using a time-varying dynamic linear model
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-12-13)
Article
Open AccessDespite the importance of computing soil pore water electrical conductivity (sp) from soil bulk electrical conductivity (sb) in ecological and hydrological applications, a good method of doing so remains elusive. The ... -
Saving runs in fractional factorial designs
(2018-12-27)
Article
Restricted access - publisher's policyWhen it is known a priori that some contrasts are negligible in a factorial design, their expressions can be used to deduce the missing results. In this article we propose a method for using this procedure when, as in the ... -
Consequences of using estimated response values from negligible interactions in factorial designs
(2018-12-21)
Article
Restricted access - publisher's policyThis article analyzes the increase in the probability of committing type I and type II errors in assessing the significance of the effects when some properly selected runs have not been carried out and their responses have ... -
Selecting significant effects in factorial designs: Lenth’s method versus the Box-Meyer approach
(Taylor & Francis, 2018-01-01)
Article
Restricted access - publisher's policyThe Lenth method is conceptually simple and probably the most common approach to analyzing the significance of the effects in factorial designs. Here, we compare it with a Bayesian approach proposed by Box and Meyer and ...
