Survival analysis is used to analyze data from patients who are followed for different periods of time and in whom the outcome interest, a dichotomous event, may or not have occurred at study halted; all analysis, including dropped out, regardless duration follow-up. This article discusses basic concepts survival explains technical terms such as censoring, provides reasons why ordinary methods ...

The aim of this research was conducted to determine the factors that influence resilience car loan debtors in an area. method used is semiparametric Cox regression on secondary data, WAREHOUSE consisting customer profile (demography) and historical payment 25 observed variables. model study a proportional hazard model. Based description it shows there risk defaulting who have been past due comp...

The asymmetry of residuals about the origin is a severe issue in estimating Box-Cox transformed model. In framework uncertainty theory, there are such theoretical issues regarding least-squares estimation (LSE) and maximum likelihood (MLE) linear models after transformation on response variables. Heretofore, only weighting methods for analysis have been available. This article proposes an uncer...

The Cox proportional hazards (PH) model usually assumes linearity of the covariates on the log hazard function, which may be violated because linearity cannot always be guaranteed. We propose a partially linear single-index proportional hazards regression model, which can model both linear and nonlinear covariate effects on the log hazard in the proportional hazards model. We adopt a polynomial...

The peripheral blood neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR), and platelet to lymphocyte ratio (PLR) have been reported to correlate with the prognosis of many malignancies. This study evaluated the prognostic value of pretreatment NLR, LMR, and PLR in nasopharyngeal carcinoma (NPC). A retrospective analysis of clinical and pathological data of 140 NPC patients ...

Preoperative serum lactate dehydrogenase (LDH) has been used as a prognostic indicator for patients with hepatocellular carcinoma (HCC) treated with sorafenib or undergoing transcatheter arterial chemoembolization, but its significance in predicting survival of HCC patients who received curative resection remains undefined. A total of 683 patients with histopathologically confirmed HCC were enr...

BACKGROUND Most reports regarding the obesity paradox have focused on body mass index (BMI) to classify obesity and the prognostic values of other indirect measurements of body composition remain poorly examined in heart failure (HF). OBJECTIVE To evaluate the association between BMI and other indirect, but easily accessible, body composition measurements associated with the risk of all-cause...
