Identification of causal intervention effects under contagion
Defining and identifying causal intervention effects for transmissible infectious disease outcomes is challenging because a treatment – such as a vaccine – given to one individual may affect the infection outcomes of others. Epidemiologists have proposed

Attributable fraction and related measures: Conceptual relations in the counterfactual framework
The attributable fraction (population) has attracted much attention from a theoretical perspective and has been used extensively to assess the impact of potential health interventions. However, despite its extensive use, there is much confusion about its

Towards Prediction of HCV Therapy Efficiency
We investigate a correlation between genetic diversity of hepatitis C virus population and the level of viral RNA accumulation in patient blood. Genetic diversity is defined as the mean Hamming distance between all pairs of virus RNA sequences representing the population. We have found that a low Hamming distance (i.e. low genetic diversity) correlates

Minimally capturing heterogeneous complier effect of endogenous treatment for any outcome variable
When a binary treatment DD is possibly endogenous, a binary instrument δ\delta is often used to identify the “effect on compliers.” If covariates XX affect both DD and an outcome YY, XX should be controlled to identify the “XX-conditional complier ...

Solving the 100 Swiss Francs Problem [PDF]
Sturmfels offered 100 Swiss Francs in 2005 to a conjecture, which deals with a special case of the maximum likelihood estimation for a latent class model.

Inferences for Joint Modelling of Repeated Ordinal Scores and Time to Event Data
In clinical trials and other follow‐up studies, it is natural that a response variable is repeatedly measured during follow‐up and the occurrence of some key event is also monitored. There has been a considerable study on the joint modelling these measures together with information on covariates.

Optimal balancing of time-dependent confounders for marginal structural models
Marginal structural models (MSMs) can be used to estimate the causal effect of a potentially time-varying treatment in the presence of time-dependent confounding via weighted regression.

In this paper, we study a deterministic method for particle transport in biological tissues. The method is specifically developed for dose calculations in cancer therapy and for radiological imaging. Generalized Fokker–Planck (GFP) theory [Leakeas and Larsen, Nucl. Sci. Eng. 137 (2001), pp.
