Nonlinear regression is a form of regression analysis in which data fit to a model is expressed as a mathematical function.

The extension of measures based on case deletion from the linear to the nonlinear model usually involve linear approximation. In this paper, the geometry of case deletion is studied with a view to ...

Certain important nonlinear regression models lead to biased estimates of treatment effect, even in randomized experiments, if needed covariates are omitted. The asymptotic bias is determined both for ...
