We study the role of age, re-election, gender, education, profession, party affiliation, area of election and different electoral systems on the political survival of 7127 members of the Italian Chamber of Deputies and Senate, observed from 1946 to 2013. Our results suggest that theories...

The introduction of unemployment insurance savings accounts (UISA) in Chile in October 2002 introduced more comprehensive unemployment protection while decreasing the opportunity costs of job change. Being the first to empirically investigate the effect of UISA on employment duration, this paper...

Ein niedrigerer Bildungsabschluss der Mutter geht mit einer geringeren Lebenserwartung einher. Personen, die eine Mutter mit einem Volksschul- oder gar keinem Schulabschluss haben, sterben im Alter ab 65 Jahren im Durchschnitt zwei Jahre früher als Personen, deren Mütter mindestens einen...

The article empirically examines the timing of initial decisions to adopt food safety systems and subsequent decisions to maintain the certification. Survival models are used to evaluate firm-level decisions among seafood processors in the Philippines. Whereas initial certification decisions...

Modern Engineering Asset Management (EAM) requires the accurate assessment of current and the prediction of future asset health condition. Suitable mathematical models that are capable of predicting Time-to-Failure (TTF) and the probability of failure in future time are essential. In traditional...

The standard Cox proportional hazards model has been extended by functionally describable interaction terms. The first of which are related to neural networks by adopting the idea of transforming sums of weighted covariables by means of a logistic function. A class of reasonable weight...

Dependent censoring occurs in longitudinal studies of recurrent events when the censoring time depends on the potentially unobserved recurrent event times. To perform regression analysis in this setting, we propose a semiparametric joint model that formulates the marginal distributions of the...

This research deals with some statistical modeling problems that are motivated by credit risk analysis. Credit risk modeling has been the subject of considerable research interest in finance and has recently drawn the attention of statistical researchers. In the first chapter, we provide an...

In tumorigenicity experiments, a complication is that the time to event is generally not observed, so that the time to tumor is subject to interval censoring. One of the goals in these studies is to properly model the effect of dose on risk. Thus, it is important to have goodness of fit...
