INFERENCE FOR NORMAL MIXTURES IN MEAN AND VARIANCE

- Jiahua Chen, Xianming Tan, Runchu Zhang
- Mathematics
- 2008

A finite mixture of normal distributions, in both mean and variance parameters, is a typical finite mixture in the location and scale families. Because the likelihood function is unbounded for any… Expand

- Medicine
- NeuroImage: Clinical
- 30 August 2014

Background Arterial spin labeling (ASL) perfusion-weighted imaging (PWI) by magnetic resonance imaging (MRI) has been shown to be useful for identifying asphyxiated newborns at risk of developing… Expand

Intraventricular hemorrhage in asphyxiated newborns treated with hypothermia: a look into incidence, timing and risk factors

- Ghalia Al Yazidi, E. Boudes, Xianming Tan, C. Saint-Martin, M. Shevell, P. Wintermark
- Medicine
- BMC Pediatrics
- 28 August 2015

BackgroundIntraventricular hemorrhage (IVH) is uncommon in term newborns. Asphyxia and hypothermia have been mentioned separately as possible risk factors of IVH, since they might cause fluctuations… Expand
