Comparing penalized splines and fractional polynomials for flexible modelling of the effects of continuous predictor variables
Strasak, Alexander; Umlauf, Nikolaus; Pfeiffer, Ruth; … - 2010
P(enalized)-splines and fractional polynomials (FPs) have emerged as powerful smoothing techniques with increasing … restricted maximum likelihood (REML) for smoothing parameter selection. We evaluated the ability of P-splines and FPs to recover … features of the approaches in a real dataset. -- generalized additive models ; GAMs ; simulation ; smoothing …

Estimating Fiscal Multipliers : News from a Nonlinear World
Caggiano, Giovanni - 2014
We estimate nonlinear VARs to assess to what extent fiscal spending multipliers are countercyclical in the United States. We deal with the issue of non-fundamentalness due to fiscal foresight by appealing to sums of revisions of expectations of fiscal expenditures. This measure of anticipated...

A Comparison of Three Models to Predict Liquidity Flows between Banks Based on Daily Payments Transactions
Triepels, Ron - 2016
The analysis of payment data has become an important task for operators and overseers of financial market infrastructures. Payment data provide an accurate description of how banks manage their liquidity over time. In this paper we compare three models to predict future liquidity flows from...

Capturing the zero: A new class of zero-augmented distributions and multiplicative error processes
Hautsch, Nikolaus; Malec, Peter; Schienle, Melanie - 2010
We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed on high frequencies, such as cumulated trading volumes or the time between potentially...

Capturing the zero: A new class of zero-augmented distributions and multiplicative error processes
Hautsch, Nikolaus; Malec, Peter; Schienle, Melanie - 2011
We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed at high frequencies, such as cumulated trading volumes. We introduce a flexible point-mass...
