Abstract Clusterwise regression is an approach to analysis based on finite mixtures which generally employed when sample observations come from a population composed of several unknown sub-populations. Whenever the response continuous, Gaussian clusterwise linear models are usually employed. Such have been recently robustified with respect possible presence mild outliers in However, some fields...

This paper presents an empirical examination of firm characteristic determinants of the capital structure of a sample of 299 Irish small and medium sized firms (SMEs). Hypotheses formulated from pecking order and agency theories incorporating a financial growth life cycle approach are tested on a number of multivariate regression models. Results suggest that age, size, level of intangible activ...

almost ideal demand system (aids) and rotterdam model have been employed to (by means of seemingly unrelated regression (sur) estimate the function related to milk and dairy products in the urban societies of iran for years 1982 to 2009. cross and cross price elasticities have been evaluated too. results indicated that during the study period, share of milk products in household budget was more...

We propose an efficient semiparametric estimator for the coefficients of a multivariate linear regression model — with a conditional quantile restriction for each equation — in which the conditional distributions of errors given regressors are unknown. The procedure can be used to estimate multiple conditional quantiles of the same regression relationship. The proposed estimator is asymptotical...

Ethiopia is currently implementing its growth and transformation plan II to boost economic over time join the middle-income countries within a few years. It believed that this objective can be realised if country make substantial amount of savings. In cognizant this, study was undertaken investigate nexus between formal informal savings determinants saving in case Sinana District. A multi-stage...

The article examines the link between workplace disability (WD) and job satisfaction (JS) using data from WERS2011. Controlling for a rich set of characteristics including organisational culture, study finds significant negative relationship JS share disabled respondents within workplaces. Notably, Seemingly Unrelated Regression (SUR)-based analysis distinguishing non-disabled reveals that foun...

Introduction For the analysis of clinical effects, multiple imputation (MI) missing data was shown to be unnecessary when using longitudinal linear mixed-models (LLM). It remains unclear whether this also applies cost estimates from trial-based economic evaluations, that are generally right-skewed. Therefore, study aimed assess MI is required prior LLM analyzing cost-effectiveness data. Methods...

Higher social capital is associated with improved mental and physical health and reduced risk of premature mortality. We explored the relationship between five measures of structural social capital and 1) intermediate health outcomes (elevated C-reactive protein, cholesterol, blood pressure, and serum fibrinogen) and 2) distal outcomes (cardiovascular and all cause mortality). We did so using t...

A nonlinear equation system for individual tree diameter growth and mortality of natural Mongolian oak forests was developed based on 13,360 observations from 195 permanent sample plots in Northeast China. Weighted regression was used in a distance-independent diameter growth equation for dealing with heterocedasticity. Since diameter growth and mortality models have common predictors including...
