Hi R-users,
I was plotting the differences of the variances of the three estimators- T^(1),
T^(2), T^(3), ofcourse taking two at a time. I was using the expression() in
the legend function in order to show which line correspond to which of the
difference, but the following that I had used didn't gave desired result. I
would be grateful, if you help me out.
plot(n, pg, type="l",xlab="n",ylab="Differences of the
variances",ylim=c(-0.0012,0.0023), xlim=c(0,60));
lines(gs,lty = 2)
lines(ps,lty=5)
legend(30, 0.0021, expression( c ( var(t^(3))-var(t^(2)),
var(t^(2))-var(t^(1))), var("t^(3))-var(t^(1)) ) ), lty=c(1,2,5))
Thanks.
Shant
