We apply the univariate sliced inverse regression (SIR) to survival data. Our approach is different from the other papers on this subject. The right-censored observations are taken into account during the slicing of the survival times by assigning each of them with equal weight to all of the slices with longer survival. We test this method with different distributions for the two main survival ...

Parametric models have been suggested as an alternative to conventional life table techniques for interpretation of observed survival patterns in cancer. This paper extends earlier work on breast cancer by studying the fit of Boag's lognormal model to the survival of 8,170 breast cancer cases reported to the Swedish Cancer Registry during 1961-1963. The model was also used to analyse the upward...

AIM This study was proposed for estimation of survival time in patients with stomach adenocarcinoma. BACKGROUND North of Iran has a high mortality rate of stomach adenocarcinoma. PATIENTS AND METHODS The study was historical cohort. The samples were the patients with stomach adenocarcinoma referred to Tooba Clinic between three years (2007-2010). Survival estimates were calculated using the...

BACKGROUND Colon cancer is the third cause of cancer deaths. Although colon cancer survival time has increased in recent years, the mortality rate is still high. The Cox model is the most common regression model often used in medical research in survival analysis, but most of the time the effect of at least one of the independent factors changes over time, so the model cannot be used. In the cu...

DesignScript, as the name suggests, is positioned at the intersection of design and programming. DesignScript can be viewed as part of the continuing tradition of the development of parametric and associative modeling tools for advanced architectural design and building engineering. Much of the thought processes that contribute to the effective use of DesignScript builds on the tradition of par...

We describe a framework for robust kinematic design based on tolerance analysis and parametric design via configuration space manipulation. The input is a parametric model of a planar mechanical system comprised of lower and higher kinematic pairs in open or closed loops. The robust synthesis task is to find a nominal design that functions correctly despite small parameter variations. This task...
