Estimation of seasonal fractionally integrated processes
(ELSEVIER SCIENCE BV, 2006)
This paper discusses the estimation of fractionally integrated processes with seasonal components. In order to estimate the fractional parameters, we propose several estimators obtained from the regression of the log-periodogram ...
Prioritizing versions for performance regression testing: the Pharo case
(Elsevier, 2020)
Context: Software performance may suffer regressions caused by source code changes. Measuring performance at each new software version is useful for early detection of performance regressions. However, systematically running ...
Generalized log-gamma regression models with cure fraction
(SPRINGER, 2009)
In this paper, the generalized log-gamma regression model is modified to allow the possibility that long-term survivors may be present in the data. This modification leads to a generalized log-gamma regression model with ...
Fractional polynomial response surface models
(2005-03-01)
Second-order polynomial models have been used extensively to approximate the relationship between a response variable and several continuous factors. However, sometimes polynomial models do not adequately describe the ...

A log-linear regression model for the beta-Birnbaum-Saunders distribution with censored data
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The beta-Birnbaum-Saunders (Cordeiro and Lemonte, 2011) and Birnbaum-Saunders (Birnbaum and Saunders, 1969a) distributions have been used quite effectively to model failure times for materials subject to fatigue and lifetime ...
