The family of density power divergences is an useful class which generates robust parameter estimates with high efficiency. None of these divergences require any non-parametric density estimate to carry out the inference procedure. However, these divergences have so far not been used effectively...

Graph-theoretic constructs are widely used in the modeling and analysis of systems. However, most existing constructs are not suitable for the analysis of systems where relationships between sets of elements have to be represented and manipulated. Such relationships occur commonly in the...

We highlight the role of local instrumental variable (LIV) methods in exploring treatment effect heterogeneity using an empirical example of evaluating the use versus non-use of prehospital intubation (PHI) in patients with traumatic injury on inpatient mortality. We find evidence that the...
