This paper combines the least squaress estimate, least absolute deviation estimate, least median estimate with Bootstrap method. When the overall error distribution is unknown or it is not the normal distribution, we estimate the regression coefficient and confidence interval of coefficient, and through data simulation, obtain Bootstrap method, which can improve stability of regression coeffici...

On the basis of fuzzy regression, computational models in intelligence such as neural networks have the capability to be applied to nonlinear interval regression analysis for dealing with uncertain and imprecise data. When training data are not contaminated by outliers, computational models perform well by including almost all given training data in the data interval. Nevertheless, since traini...

BACKGROUND AND OBJECTIVES Current therapy for IgA nephropathy mainly includes renin-angiotensin system inhibitors and adding steroids for patients with persistent proteinuria. This study aimed to evaluate kidney disease progression and its risk factors in a Chinese cohort under current therapy.

A study was undertaken in southern peninsular state of India, the Tamil Nadu State, to assess the farmers’ “Willingness to pay” (WTP) for receiving annual health care services to their dairy animals. The districts of the state were categorized as “Livestock developed” (LD) and “Livestock under developed” (LUD) based on initial base line developed. Contingent valuation (CV) approach was used to ...
