Fitzenberger, Bernd; Wilke, Ralf A. - Zentrum für Europäische Wirtschaftsforschung (ZEW) - 2005
Quantile regression methods are emerging as a popular technique in econometrics and biometrics for exploring the distribution of duration data. This paper discusses quantile regression for duration analysis allowing for a flexible specification of the functional relationship and of the error...

A Note on Implementing Box-Cox Quantile Regression
Wilke, Ralf A.; Fitzenberger, Bernd; Zhang, Xuan - Zentrum für Europäische Wirtschaftsforschung (ZEW) - 2004
The Box-Cox quantile regression model using the two stage method introduced by Chamberlain (1994) and Buchinsky (1995) provides an attractive extension of linear quantile regression techniques. However, a major numerical problem exists when implementing this method which has not been addressed...

Considerations on partially identified regression models
Cerquera, Daniel; Laisney, François; Ullrich, Hannes - Zentrum für Europäische Wirtschaftsforschung (ZEW) - 2012
Motivated by Manski and Tamer (2002) and especially their partial identification analysis of the regression model where one covariate is only interval-measured, we offer several contributions. Manski and Tamer (2002) propose two estimation approaches in this context, focussing on general...
