Economic theory suggests that an extension of the maximum length of entitlement for unemployment benefits increases the duration of unemployment. Empirical results for the reform of the unemployment compensation system in Germany during the 1980s are less clear. The analysis in this paper is motivated by the controversial empirical findings and by recent developments in econometrics for partial...

background & aim: esophageal cancer is one of the main common causes of death. the high prevalence of esophageal cancer in northern iran is an important public health problem. the main aim of this paper was to assess the factors affecting survival of  atients with esophageal cancer in neighbor provinces around the caspian sea using weibull mixture cure model and mixture cure model based on a no...

Boundary prediction in images as well as video has been a very active topic of research and organizing visual information into boundaries and segments is believed to be a corner stone of visual perception. While prior work has focused on predicting boundaries for observed frames, our work aims at predicting boundaries of future unobserved frames. This requires our model to learn about the fate ...

The underlying idea of Reich, Fuentes, and Dunson (2009) to use the asymptotic normal approximation of the quantile regression estimator as a “substitute” likelihood can be regarded as a convenient dumbing-down of the Jeffrey’s idea elaborated by Lavine (1995) and Dunson and Taylor (2005). The obvious disadvantage of the original Jeffrey’s suggestion is that it is difficult to compute/update th...

Background: Acute Myeloid leukemia (AML) is the most prominent acute in adults. In United States, we experience over 20,000 cases per year. Over past decade, improvements diagnosis of subtypes AML and advances therapeutic approaches have improved outlook for patients with AML. However, despite these advancements, survival rate among who are less than 65 years age only 40 percent. Purpose: The p...

Multilevel mixed effects survival models are used in the analysis of clustered survival data, such as repeated events, multi-centre clinical trials, and Individual Participant Data (IPD) meta-analyses, to investigate heterogeneity in baseline risk and covariate effects. In this paper we extend parametric frailty models including the exponential, Weibull, and Gompertz proportional hazards models...

results survival probabilities at different times were determined using the cox proportional hazards and a neural network with three nodes in the hidden layer; the ratios of standard errors with these two methods to the kaplan-meier method were 1.1593 and 1.0071, respectively, revealed a significant difference between cox and kaplan-meier (p < 0.05) and no significant difference between cox and...

Survival analysis is a set of methods used for analysis of the data which exist until the occurrence of an event. This study aimed to compare the results of the use of the semi-parametric Cox model with parametric models to determine the factors influencing the length of stay of patients in the inpatient units of Women Hospital in Tehran, Iran. In this historical cohort study all 3421 charts of...

background: breast cancer (bc) is the second most commonly diagnosed cancer after lung cancer. survival of bc patients is affected by intermediate events. this study was aimed to investigate the disease course of primary non-metastatic bc patients with first recurrence of the tumor (frt) as the intermediate event using the illness- death model. methods: this retrospective cohort study was condu...

the data set employed in this study was comprised of a number of 6,800 records of lamb’s longevity and their survival rate, collected from 1989 through 2009, from the lori-bakhtiari experimental flock at the shooli station in shahrekord, iran. the data were analyzed using linear models and proportional hazard models with weibull function. these models included fixed factors and direct additive ...
