We consider density deconvolution with zero-mean Laplace errors in the context of an error component regression model. We adapt the minimax deconvolution methods of Meister (2006) to allow for unknown variance of the Laplace errors. We propose a semi-uniformly consistent deconvolution estimator for an ordinary smooth target density and a modified “variance truncation device" for the unknown Laplace error variance. We provide practical guidance for the choice of smoothness parameters of the target density. A simulation study and applications to a stochastic frontier model of US banks and a statistical measurement error model of daily saturated fat intake are provided.
