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))
Have you consider offering a toy set of objects which defines "t",
"n", and "pg".
Thanks.
Shant
