This paper contributes to classification and identification in modern finance through advanced optimization. In the last few decades, financial misalignments and, thereby, financial crises have been increasing in numbers due to the rearrangement of the financial world. In this study, as one of the most remarkable of these, countries' debt crises, which result from illiquidity, are tried to predict with some macroeconomic variables. The methodology consists of a combination of two predictive regression models, logistic regression and robust conic multivariate adaptive regression splines (RCMARS), as linear and nonlinear parts of a generalized partial linear model. RCMARS has an advantage of coping with the noise in both input and output data and of obtaining more consistent optimization results than CMARS. An advanced version of conic generalized partial linear model which includes robustification of the data set is introduced: robust conic generalized partial linear model (RCGPLM). This new model is applied on a data set that belongs to 45 emerging markets with 1,019 observations between the years 1980 and 2005.

A NEW ROBUST OPTIMIZATION TOOL APPLIED ON FINANCIAL DATA Ozmen, A.; Weber, Gerhard Wilhelm; Karimov, A. (2013-07-01) Recent financial crises, with an increased volatility and, hence, uncertainty factors, have introduced a high "noise" into the data taken from the financial sectors and overall from any data related to the financial markets, so that the known statistical models do not give trustworthy results. As we know the solutions of the optimization problem can show a remarkable sensitivity to perturbations, coming from the data, in the parameters of the problem. To overcome this kind of difficulties, the model identif...
Robust optimization in spline regression models for multi-model regulatory networks under polyhedral uncertainty Ozmen, Ayse; Kropat, Erik; Weber, Gerhard Wilhelm (2017-01-01) In our study, we integrate the data uncertainty of real-world models into our regulatory systems and robustify them. We newly introduce and analyse robust time-discrete target-environment regulatory systems under polyhedral uncertainty through robust optimization. Robust optimization has reached a great importance as a modelling framework for immunizing against parametric uncertainties and the integration of uncertain data is of considerable importance for the model's reliability of a highly interconnected ...
ON FOUNDATIONS OF PARAMETER ESTIMATION FOR GENERALIZED PARTIAL LINEAR MODELS WITH B-SPLINES AND CONTINUOUS OPTIMIZATION TAYLAN, PAKİZE; Weber, Gerhard Wilhelm; Liu, Lian (2010-02-04) Generalized linear models are widely-used statistical techniques. As an extension, generalized partial linear models utilize semiparametric methods and augment the usual parametric terms by a single nonparametric component of a continuous covariate. In this paper, after a short introduction, we present our model in the generalized additive context with a focus on penalized maximum likelihood and on the penalized iteratively reweighted least squares (P-IRLS) problem based on B-splines which is attractive for...
The Impact of Modeling on Robust Inventory Management Under Demand Uncertainty Solyali, Oguz; Cordeau, Jean-Francois; Laporte, Gilbert (2016-04-01) This study considers a basic inventory management problem with nonzero fixed order costs under interval demand uncertainty. The existing robust formulations obtained by applying well-known robust optimization methodologies become computationally intractable for large problem instances due to the presence of binary variables. This study resolves this intractability issue by proposing a new robust formulation that is shown to be solvable in polynomial time when the initial inventory is zero or negative. Becau...
Advances in robust identification of spline models and networks by robust conic optimization, with applications to different sectors Özmen, Ayşe; Wilhelm Weber, Gerhard; Department of Scientific Computing (2015) Uncertainty is one of the characteristic properties in the area of high-tech engineering and the environment, but also in finance and insurance, as the given data, in both input and output variables, are affected with noise of various kinds, and the scenarios which represent the developments in time, are not deterministic either. Since the global environmental and economic crisis has caused the necessity for an essential restructuring of the approach to risk and regulation in these areas, core elements of n...
