Give missings a chance : combined stochastic and rule-based approach to improve regression models with mismeasured monotonic covariates without side information
Dlugosz, Stephan - 2011
Register data are known for their large sample size and good data quality. The measurement accuracy of variables highly depends on their high importance for administrative processes. The education variable in the IAB employment sub-sample is an example for information that is gathered without a...

Imposing and testing curvature conditions on a Box-Cox function
Koebel, Bertrand M.; Falk, Martin; Laisney, François - 2000
We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...

A note on implementing box-cox quantile regression
Fitzenberger, Bernd (contributor);  … - 2005 - Rev. version
The Box-Cox quantile regression model using the two stage method suggested by Chamberlain (1994) and Buchinsky (1995) provides a flexible and numerically attractive extension of linear quantile regression techniques. However, the objective function in stage two of the method may not exists. We...

Generalised partially linear regression with misclassified data and an application to labour market transitions
Dlugosz, Stephan; Mammen, Enno; Wilke, Ralf A. - 2015
We consider the semiparametric generalised linear regression model which has mainstream empirical models such as the (partially) linear mean regression, logistic and multinomial regression as special cases. As an extension to related literature we allow a misclassified covariate to be interacted...
