Hi,

This is my first post here and I hope that I am in the correct subforum .

So, I have this equation:$\displaystyle r_{Gm}(y)=\left \{ Y_{j}|D_{Gm}(Y_{j})\leq D_{Gm}(y),j=1,...,m \right \}/m$

Also there is a # before the curly bracket, I don't know why the equation writer won't allow me to put it.

Now to the question. Disregard what the variables are, I just want to know how this equation works. How can I interpret it? If I have the variables how do I get rGm?

Thank you for your help.
