Wang, Xiao Ming et Zhou, Wang, Bootstrap Approximation to the Distribution of M-estimates in a Linear Model, Acta mathematica Sinica. English series (Print) , 20(1), 2004, pp. 93-104
The authors establish the approximations to the distribution of M-estimates in a linear model by the bootstrap and the linear representation of bootstrap M-estimation, and prove that the approximation is valid in probability 1. A simulation is made to show the effects of bootstrap approximation, randomly weighted approximation and normal approximation.
