Dear all,
I am running a code using bootstraps for estimating standard errors but the
mac crashes. When I use small number of bootstraps (100) it works fine but
if I increase that number it crashes.
Thanks in advance
dimitris
The code, the error and my mac characteristics are the following:
##code#
qr.1- rq(y~factor(year)+factor(state)+x1+I(x^2)+I(x^3), tau=0.05,
data=data1)
s.qr1.05 - summary(qr.1, se=boot, R=1000)$coefficient
##error#

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
