Abstract questionnaires and FS-decision digraphs
Jiaye Chen, Suzan Kadri, Mateja Šajna +1
A questionnaire is a sequence of multiple choice questions aiming to collect data on a population. We define an abstract questionnaire as an ordered pair , where …
Estimation for recurrent events through conditional estimating equations
Ioana Schiopu-Kratina, Hai Yan Liu, Mayer Alvo +1
We present new estimators for the statistical analysis of the dependence of the mean gap time length between consecutive recurrent events, on a set of explanatory random variables…
Asymptotic results with estimating equations for time-evolving clustered data
Laura Dumitrescu, Ioana Schiopu-Kratina
We study the existence, strong consistency and asymptotic normality of estimators obtained from estimating functions, that are p-dimensional martingale transforms. The problem is m…
Strong consistency and optimality for generalized estimating equations with stochastic covariates
Laura Dumitrescu, Ioana Schiopu-Kratina
In this article we study the existence and strong consistency of GEE estimators, when the generalized estimating functions are martingales with random coefficients. Furthermore, we…
The asymptotically optimal estimating equation for longitudinal data. Strong Consistency
R. M. Balan, L. Dumitrescu, I. Schiopu-Kratina
In this article, we introduce a conditional marginal model for longitudinal data, in which the residuals form a martingale difference sequence. This model allows us to consider a r…
Asymptotic results with generalized estimating equations for longitudinal data
R. M. Balan, I. Schiopu-Kratina
We consider the marginal models of Liang and Zeger [Biometrika 73 (1986) 13-22] for the analysis of longitudinal data and we develop a theory of statistical inference for such mode…
