Analyse von Erwartungen in der Volkswirtschaft mit Partial-Least-Squares-Modellen

Ruge, Marcus; Strohe, Hans Gerhard - 2008

Der statistische Diskussionbeitrag untersucht, ob und wie sich Erwartungen und Stimmungen in der Wirtschaft bilden bzw. von welchen volkswirtschaftlichen Größen sie abhängen. Als Methodik werden Partial Least Squares (PLS) Modelle genutzt, eine Modellklasse der Pfadanalyse mit latenten...

A partially linear approach to modelling the dynamics of spot and futures prices

Gaulke, Jürgen (contributor); Theissen, Erik (contributor) - 2008

In this paper we consider the dynamics of spot and futures prices in the presence of arbitrage. We propose a partially linear error correction model where the adjustment coefficient is allowed to depend non-linearly on the lagged price difference. We estimate our model using data on the DAX...

How are comfort and safety perceived by inland waterway transport passengers?

Márquez, Luis; Cantillo, Víctor; Arellana, Julián - In: Transport Policy 36 (2014) C, pp. 46-52

The geographical conditions of Colombia limit connectivity among regions, making communication between different areas of the country difficult. Although Colombia has a major waterway system that could facilitate regional communication, much of the territory is functionally disjointed, which is...

Synopsis of bicycle demand in the City of Toronto: Investigating the effects of perception, consciousness and comfortability on the purpose of biking and bike ownership

Habib, Khandker Nurul; Mann, Jenessa; Mahmoud, Mohamed; … - In: Transportation Research Part A: Policy and Practice 70 (2014) C, pp. 67-80

This paper provides an empirical basis for the evaluation of policies and programs that can increase the usage of bikes for different purposes as well as bike ownership. It uses an integrated econometric model of latent variable connecting multiple discrete choices. Empirical models are...

Contrasting imputation with a latent variable approach to dealing with missing income in choice models

Sanko, Nobuhiro; Hess, Stephane; Dumont, Jeffrey; Daly, … - In: Journal of choice modelling 12 (2014) C, pp. 47-57

Income is a key variable in many choice models. It is also one of the most salient examples of a variable affected by data problems. Issues with income arise as measurement errors in categorically captured income, correlation between stated income and unobserved variables, systematic over- or...

Using semi-open questions to integrate perceptions in choice models

Glerum, Aurélie; Atasoy, Bilge; Bierlaire, Michel - In: Journal of choice modelling 10 (2014) C, pp. 11-33

This research investigates the measurement of perceptions by means of adjectives freely reported by respondents in semi-open questions. It involved the use of semi-open responses of 1763 Swiss individuals to develop indicators for a latent variable representing the perception of comfort of...

Modeling rating data with Nonlinear CUB models

Manisera, Marica; Zuccolotto, Paola - In: Computational Statistics & Data Analysis 78 (2014) C, pp. 100-118

A general statistical model for ordinal or rating data, which includes some existing approaches as special cases, is proposed. The focus is on the CUB models and a new class of models, called Nonlinear CUB, which generalize CUB. In the framework of the Nonlinear CUB models, it is possible to...

Extended stochastic volatility models incorporating realised measures

Venter, J.H.; de Jongh, P.J. - In: Computational Statistics & Data Analysis 76 (2014) C, pp. 687-707

Extended stochastic volatility models are studied which use the daily returns as well as the volatility information in intraday price data summarised in terms of a number of realised measures. These extended models treat the logarithm of daily volatility as a latent process with autoregressive...
