Epidemiology of miscarriage
Miscarriages account for about one in six/one in seven pregnancies, and probably over one in five excluding induced abortions, i.e. over 20 million events per year. However, any precise and valid estimate is made difficult by uncertainties in diagnosis, ascertainment, distinction in registration between induced and spontaneous abortions, and certification. These uncertainties vary across geographic region, country and socio-economic status..

On robust estimation via pseudo-additive information
We consider a robust parameter estimator minimizing an empirical approximation to the q-entropy and show its relationship to minimization of power divergences through a simple parameter transformation. The estimator balances robustness and efficiency through a tuning constant q and avoids kernel density smoothing. We derive an upper bound to the estimator mean squared error under a contaminated reference model and use it as a min-max criterion for selecting
