Abstract The beta distribution is a versatile function that accommodates a broad range of probability distribution shapes. Beta regression based on the beta distribution can be used to model a response variable y that takes values in open unit interval (0, 1). Zero/one inflated beta (ZOIB) regression models can be applied when y takes values from closed unit interval [0, 1]. The ZOIB model is b...
One of the basic types portfolio valuation as well individual company shares is CAPM (Capital Asset Pricing) model, which uses a well-known measure systemic risk in its analysis, beta. The model analysis link between (beta) and expected market return. Guided by this monthly returns selected on Belgrade Stock Exchange period from 2011 to 2021 was performed research. In research, beta coefficient...
Serum beta-2 microglobulin levels predict mortality in dialysis patients: results of the HEMO study.
In the randomized Hemodialysis (HEMO) Study, chronic high-flux dialysis, as defined by higher beta-2 microglobulin (beta(2)M) clearance, compared with low-flux dialysis did not significantly alter all-cause mortality in the entire cohort but was associated with lower mortality in long-term dialysis patients. This analysis examined the determinants of serum beta(2)M levels and the associations o...
background: breast cancer is the most common cancer after lung cancer and the second cause of death. in this study we compared weibull and lognormal cure models with cox regression on the survival of breast cancer. study design: a cohort study. methods: the current study retrospective cohort study was conducted on 140 patients referred to ali ibn abitaleb hospital, rafsanjan southeastern iran f...
background: we designed an algorithmic model based on the logistic regression analysis and a non-algorithmic model based on the artificial neural network (ann). materials and methods: the ability of these models was compared together in clinical application to differentiate malignant from benign breast tumors in a study group of 161 patients' records. each patient’s record consisted of 6 s...
In this poster we study active learning for supervised regression algorithms. We focus on a particular problem where the regression is constrained to an interval. This is the case, for instance, when the objective is to estimate the probability of success of a certain event given a set of input points. The regression problem is, thus, constrained to the zero-one interval and the training exampl...
background: the purpose of this study is to determine association between personal, family, neighborhood, and social network characteristics and perceived intimacy in the neighborhood by the women. methods: in this cross‑sectional study, we applied a two‑stage sampling method to choose a representative sample of 150 married women and housewives, aged 15 to 49 years, who had education between si...
Loss given default (LGD) is a key parameter in credit risk management to calculate the required regulatory minimum capital. The internal ratings-based (IRB) approach under Basel II allows institutions determine loss on their own. In this study, we have estimated LGD for portfolio data by using beta regression with precision (∅) and mean (μ). was obtained from banking institution Jordan; period ...
