This process allows … WebHere is how the statistical functionals and the bootstrap is connected. In estimating the parameter = T target(F), we often use a plug-in estimate from the EDF b n= T target(Fb n) (just think of how we estimate the sample mean). In this case, the bootstrap estimator, the estimator using the bootstrap sample, will be b n = T target(Fb n); trade federation theme
