# [Tex/LaTex] Bug related to \hat{} in amsmath

symbols

I'm trying to typeset an equation that contains the following:

\begin{align*}
\hat{\E[(R_{i}-\hat R_{i})^{2}]}
\end{align*}


However, this is what I get

Is this a bug? Is there any way around it? I'd like the "hat" to be over the whole expression, not just the expectation operator which I've defined as:

\newcommand{\E}{\mathbb{E}}


\widehat{\E[(R_{i}-\hat{R}_{i})^{2}]}
