A macro-DAG structure based mixture model
In the context of unsupervised classification of multidimensional data, we revisit the classical mixture model in the case where the dependencies among the random variables are described by a DAG structure. The structure is considered at two levels, the original DAG and its macro-representation. This twolevel representation is the main base of the proposed mixture model. To perform unsupervised...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولA regime switching macro-nance model of the term structure
This paper presents and estimates a regime switching macro- nance model of the term structure with latent and macroeconomic factors. The joint dynamics of the yield and macro factors are examined simultaneously. Both the canonical yields-only model and the macro- nance model capture two regimes in the state equation that relate to a turbulent period and a tranquil period. Statistically, the for...
متن کاملMixture-model-based signal denoising
This paper proposes a new signal denoising methodology for dealing with asymmetrical noises. The adopted strategy is based on a regression model where the noise is supposed to be additive and distributed following a mixture of Gaussian densities. The parameters estimation is performed using a Generalized EM (GEM) algorithm. Experimental studies on simulated and real signals in the context of a ...
متن کاملA SAS macro for parametric and semiparametric mixture cure models
Cure models have been developed to analyze failure time data with a cured fraction. For such data, standard survival models are usually not appropriate because they do not account for the possibility of cure. Mixture cure models assume that the studied population is a mixture of susceptible individuals, who may experience the event of interest, and non-susceptible individuals that will never ex...
