the data are 3,5,7,18,43,85,91,98,100,130,230,487, it follows an exp(lamda) model, how to use bootstrap to obtain MLE of lamda, bias, sd. Thanks a lot so far my code is obj<-boot(data,statistic,R=2000) here statistic should call a function to get an estimate of lamda I think, anyone can help ? I am new to bootstrap:) -- View this message in context: http://www.nabble.com/use-bootstrap-to-get-MLE-of-lamda-from-the-exp-model-tp16021176p16021176.html Sent from the R help mailing list archive at Nabble.com.
