This paper focuses on the estimation of an approximated function and its derivatives. Let us assume that the data-generating process can be described by a family of regression models null, where a is a multi-index of differentiation such that D_αnull(x_i) is the αth derivative of null(<italic>x</italic>) with...

The object of this paper is to report, for a simple testing problem of a unit root hypothesis, some experience regarding the numerical problems involved by using a Bayesian encompassing test, i.e., a Bayesian procedure that treats the null and the alternative hypotheses as different models, the...

We specify several variants of a structural econometric model explaining mortgage interest rates and loan sizes simultaneously. The models are estimated by simultaneous equation methods with a sample of loan files originated from a French mortgage lender. They yield estimates of the...
