Log-symmetric models with cure fraction with application to leprosy reactions data

Semiparametric Transformation Models for Survival Data with a Cure Fraction

We propose a class of transformation models for survival data with a cure fraction. The class of transformation models is motivated by biological considerations, and it includes both the proportional hazards and the proportional odds cure models as two special cases. An efficient recursive algorithm is proposed to calculate the maximum likelihood estimators. Furthermore, the maximum likelihood ...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Frailty models with a cure fraction for modeling clustered discrete survival data

Cure Rate Models – a Partial Review with an Application to Recurrent Event or Count Data

1. A.B.Shetty Memorial Institute of Dental Sciences Nitte University, Deralakatte, Mangalore, Karnataka, India. 2. Mangalore University, Karnataka, India. Abstract : Cure rate models are survival models consisting of a cured fraction and an uncured fraction. These models are being widely used in analyzing data from cancer clinical trials. A model to estimate the cure fraction was first develope...

[Leprosy reactions in discharged patients following cure by multidrug therapy].

INTRODUCTION Reactional states are the main cause of nerve lesions and incapacities provoked by leprosy. METHODS Retrospective study aimed at verifying the frequency of leprosy reactions in discharged patients following cure by multidrug therapy (MDT). RESULTS Among patients who presented reactions during treatment, 35.5% continued after MDT; of those that did not present during treatment, ...
