About
About Me
The research focus of Sunil Dhar has been on model building and inference. The inverse sampling scheme’s multivariate distribution was generalized to the new Loglinear Modeling, Soumi and Dhar (2008) and (Dhar; 1995) under the generalized inverse sampling scheme. This new multivariate distribution helps generalize other “orderk” distributions (Dhar 1996). His ongoing research involves proving existence, computing and developing robust and efficient minimum distance estimators such as L2distance type, under the following models: linear, AR [k], the additive effects outliers, and the twosample location model, Dhar and Chen (2005). He also developed functional least squares estimators under the additive effects outliers’ model. An optimization technique for the general class of sums of absolute multivariate linear functional has been developed by him. He has acquired statistical consulting experience and applies it to the health sciences. Constructing new bootstrapbased test for establishing noninferiority in clinical trials and he has developed methods training clinical staff in pharmaceutical industry to do biostatistical research, Dhar and Kianifard (2006).
