Regression analysis of multivariate panel count data.
We consider panel count data which are frequently obtained in prospective studies involving recurrent events that are only detected and recorded at periodic assessment times. The data take the form of counts of the cumulative number of events detected at each inspection time, along with explanatory covariates. Examples arise in diverse areas such as epidemiological studies, medical follow-up st...
متن کاملA Semiparametric Regression Model for Panel Count Data: When Do Pseudo-likelihood Estimators Become Badly Inefficient?
We consider estimation in a particular semiparametric regression model for the mean of a counting process under the assumption of “panel count” data. The basic model assumption is that the conditional mean function of the counting process is of the form E{N(t)|Z} = exp(θ′Z)Λ(t) where Z is a vector of covariates and Λ is the baseline mean function. The “panel count” observation scheme involves o...
متن کاملSemiparametric regression of multivariate panel count data with informative observation times
Multivariate panel count data occur in many fields such as medical and social science studies in which several outcomes of interest are measured simultaneously and repeatedly over time. When the observation times are not pre-specified, it is very likely that either the observation or follow-up times are informative about the response process. In such situations, most existing approaches either ...
متن کاملSemiparametric analysis of zero-inflated count data.
Medical and public health research often involve the analysis of count data that exhibit a substantially large proportion of zeros, such as the number of heart attacks and the number of days of missed primary activities in a given period. A zero-inflated Poisson regression model, which hypothesizes a two-point heterogeneity in the population characterized by a binary random effect, is generally...
متن کاملSemiparametric Estimation of Regression Models for Panel Data
Linear models with error components are widely used to analyze panel data. Some applications of these models require knowledge of the probability densities of the error components. Existing methods handle this requirement by assuming that the densities belong to known parametric families of distributions (typically the normal distribution). This paper shows how to carry out nonparametric estima...
