Linton, Oliver B., Mammen, E., Nielsen, J.
We derive the asymptotic distribution of a new backfitting procedure for estimating the closest additive approximation to a nonparametric regression function. The procedure employs a recent...
On estimation of monotone and concave frontier functions (1999)
Gijbels, Irène; U0046438 JFA; CORA, Mammen, E, Park, BU, Simar, L
When analyzing the productivity of firms, one may want to compare how the firms transform a set of inputs I (typically labor, energy or capital) into an output y (typically a quantity of goods...
Properties Of The Nonparametric Autoregressive Bootstrap (1998)
J. Franke, J. -p. Kreiss, E. Mammen, M. H. Neumann
. We prove geometric ergodicity and absolute regularity of the nonparametric autoregressive bootstrap process. To this end, we revisit this problem for nonparametric autoregressive processes and give...

Smoothing Splines And Shape Restrictions (1998)
Constrained smoothing splines are discussed under order restrictions on the shape of the function m. We consider shape constraints of the type m (r) 0 for r 0, i.e. positivity, monotonicity,...
Local adaptivity of kernel estimates with plug-in local bandwidth selectors (1998)
Gijbels, Irène; U0046438 JFA; CORA, Mammen, E
In non-parametric function estimation selection of a smoothing parameter is one of the most important issues. The performance of smoothing techniques depends highly on the choice of this parameter....
Mass recentred kernel smoothers (1997)
The local linear smoother usually gives better performance than the Nadaraya-Watson smoother. An exception is the case of data sparsity. Here we discuss a modification of the Nadaraya-Watson smoother...
On Qualitative Smoothness of Kernel Density Estimates. (1994)
. In this paper we give asymptotic expansions for the expected number of local extremes and inflection points of kernel density estimates. We argue that these numbers can be used as an indicator for...
Platelet function, thrombin and fibrinolytic activity in patients with heart failure (1993)
JAFRI, S. M., OZAWA, T., MAMMEN, E., LEVINE, T. B., JOHNSON, C., GOLDSTEIN, S.
Assays which detect the release of platelet proteins and of pep tides during thrombogenesis and are considered markers of activation of platelets and the coagulation system have recently been...
