ci on radius
All
I have some data that is measured in double angle space: (r,t) where r
is sqrt(x^2+y^2) and t is an angle between 0 and pi radians. There are
all sorts of ways to compute confidence intervals on the average angle
for circular data by trasforming (xbar,ybar) - the centroid in
Cartesian cooridiantes - x=r cos(2t), y=r sin(2t).
However, r is variable in my data. I would like to find a confidence
interval on r. A hypothesis test that r is not different from zero
would also be nice.
This is not homework. It is astigmatism data from manifest refractions.
r is the cylinder and t is the axis of the astigmatism.
Thanks,
Mark
