Siamak Noorbaloochi

Siamak Norbaloochi, PhD (biostatistician) is working on Bayesian least biased inference rules providing a unified theory for most powerful testing and unbiased estimation. In addition to providing statistical support for Center projects, Dr. Noorbaloochi is also working on inferential procedures for left truncated right censored ordinal count data.
