May 17, 2021 at 10:14 | comment | added | Math_Y | Why $var(x_0^2)$ is important? This maximization is known for example for simple case $\mathbf{y}=\mathbf{x}+\mathbf{z}$. | |
May 17, 2021 at 9:47 | comment | added | Math_Y | I do not understand your comment. Variance of $x_0$ is $1$ as you write. | |
May 17, 2021 at 8:45 | comment | added | Carlo Beenakker | does the maximum exist? I would think $I$ can become arbitrarily large by choosing $\mathbf{x}=(x_0,0,0,\ldots 0,0)$ with $E[x_0^2]=1$ and then giving $x_0^2$ an arbitrarily large variance. | |
