Analysis of time series and panel data is a very large area of methodology. In this brief presentation of these classes of models, I am exchanging depth for breadth in an attempt to point particular types of models that may need to investigate further in doing empirical work.

With the release of Stata 7, the glm command for fitting generalized linear models underwent a substantial overhaul. Stata 7 glm contains an expanded array of variance estimators, regression diagnostics, and other enhancements. The overhaul took place to coincide with the release of Hardin and...

When considering treatment options, a physician ideally has access to prognoses for various spans of prospective time, meaning known risks specific for these and also for both treatment and the profile of the patient. Accordingly, investigators ideally would report estimates of such risks from...

The paper examines fertility differentials among the three religion groups, Hindu, Muslim and Christian, and trends in these based on data from the National Family Health Survey (NFHS-1). [WP No. 167].

Despite the enormous increasing in Higher Education (HE) enrolment during the last decades in Portugal, retention rates remain very high when compared to most European Union countries'. This outcome is particularly meaningful for a set of 1st year's critical matters which failure severely...

In this paper, some new statistical methods are proposed, for making inferences about the parameter indexing a Cox proportional hazards marginal structural model for point exposure. Under the key assumption that unmeasured confounding is absent, we propose a new class of closed-form estimators...

Dependent censoring arises in biomedical studies when the survival outcome of interest is censored by competing risks. In survival data with microarray gene expressions, gene selection based on the univariate Cox regression analyses has been used extensively in medical research, which however,...

In a follow-up study the time-to-event may be censored either because of dropouts or the end of study is earlier. This situation is frequently modeled through a Cox-proportional hazards model including covariates, some of which are under the control of the experimenter. When the model is to be...

Purpose – The purpose of this paper is to study the optimal pricing problem that retailers are challenged with when dealing with seasonal products. The friction between expected demand and realized demand creates a risk that supply during the season is not cleared, thus forcing the retailer to...
