In applications, the linear multiple regression model is often modified to allow for nonlinearity in an independent variable. It is argued here that in practice it may often be desirable to specify a Bayesian prior that the unknown functional form is "simple" or "uncomplicated" rather than to...

We conducted the experimental parametric studies of the wind wheel aerodynamic characteristics (of Savonius rotor type) under conditions of non-reversible motion. We estimate influence of wind wheel elongation, number of blades, and their shapes on the wind energy utilisation factor. We showed...

This paper has been prepared for Handbook of Applied Economic Statistics, edited by David Giles and Aman Ullah. It considers a particular class of single-equation nonlinear multivariate models called smooth transition regression (STR) models. Inference in these models, including testing...
