The rise in contraceptive use has largely been driven by short-acting methods of contraception, despite the high effectiveness long-acting reversible contraceptives. Several countries Latin America and Caribbean have made important progress increasing modern contraceptives, but inequalities remain. We assessed prevalence demand for with data from national health surveys.
The inverse Gaussian distribution is a positively skewed probability model that has received great attention in the last 20 years. Recently, family generalizes this called type distributions been developed. new R package named <b>ig</b> designed to analyze data from distributions. This contains basic probabilistic functions, lifetime indicators and random number generator model. Also, parameter estimates diagnostics analysis can be obtained using likelihood methods by means of package. In...
Abstract The generalized Birnbaum‐Saunders (GBS) distribution is a new class of positively skewed models with lighter and heavier tails than the traditional (BS) distribution, which largely applied to study lifetimes. However, theoretical argument interesting properties GBS model have made its application possible beyond lifetime analysis. aim this paper present as useful for describing pollution data deriving positive negative moments. Based on these moments, we develop estimation...
Abstract In this paper, we discuss the class of generalized Birnbaum–Saunders distributions, which is a very flexible family suitable for modeling lifetime data as it allows different degrees kurtosis and asymmetry unimodality well bimodality. We describe theoretical developments on model including properties, transformations related analysis, shape analysis. also methods inference based uncensored censored data, diagnostics methods, goodness-of-fit tests, random number generation algorithms...
Skewed models are important and necessary when parametric analyses carried out on data. Mixture distributions produce widely flexible with good statistical probabilistic properties, the mixture inverse Gaussian (MIG) model is one of those. Transformations MIG also create new distributions, which useful in diverse situations. The aim this paper to discuss several aspects distribution for modelling positive We specifically transformations, derivation moments, fitting models, a shape analysis...
Abstract In this article, we introduce a skewed version of the sinh-normal distribution and discuss some its properties. addition, characterize an extension Birnbaum–Saunders model associated with from probabilistic viewpoint along lifetime analysis based on hazard rate. Finally, one proposed models is applied to air pollution data in order illustrate usefulness.

<h3>Objective</h3> To describe the current situation and trends in mortality due to cardiovascular disease (CVD) Americas explore their association with economic indicators. <h3>Design Setting</h3> This time series study analysed data from 21 countries region of 2000 latest available year. <h3>Main Outcomes Measures</h3> Age-adjusted death rates, annual variation rates. Regression analysis was used estimate between age-adjusted rates country income. <h3>Results</h3> Currently, CVD comprised...
<sec> <title>Objective.</title> To analyze temporal trends and inequalities in neonatal mortality between 2000 2020, to set targets for 2025 2030 the Americas. </sec> <title>Methods.</title> A descriptive ecological study was conducted using 33 countries of Americas as units analysis. Both percentage change average annual rates were estimated. Measurements absolute relative inequality based on adjusted regression models used assess cross-country social mortality. Targets reduce 2030....
In industrial statistics, there is great interest in predicting with precision lifetimes of specimens that operate under stress. For example, a bad estimation the lower percentiles life distribution can produce significant monetary losses to organizations due an excessive amount warranty claims. The Birnbaum–Saunders useful for modeling lifetime data. This because such allows us relate total time until failure occurs some type cumulative damage produced by this paper, we propose methodology...
Injuries, disabilities and deaths among motorcyclists have been rising worldwide but what is happening in the American Continent not completely known. Deaths from motorcycle crashes of Pan Health Organization database (PAHO/WHO, 1998–2010) were included an ecologic multi-national study to quantify temporal trends estimate association between riders' selected socio-economic indicators. Mortality rates increased all sub-regions. The highest increase was reported countries Andean sub-region...
BackgroundLatin America and the Caribbean present second highest adolescent fertility rate in world, only after sub-Saharan Africa, have reached third position globally incidence of motherhood adolescence. We aimed to explore trends inequities childbearing region.MethodsWe used nationally representative household surveys from Latin American countries address early (proportion women having their first livebirth before age 18 years) over generations rates (AFRs; livebirths per 1000 aged 15–19...
Although most Latin American and the Caribbean (LAC) countries made important progress in maternal child health indicators from 1990s up to 2010, little is known about such last decade. This study aims at documenting for each country as a whole, assess how within-country socioeconomic inequalities are evolving over time.We identified LAC which national survey was available between 2011-2015 second comparable 2018-2020. These included Argentina, Costa Rica, Cuba, Dominican Republic, Guyana,...
