[Tex/LaTex] move the hat symbol vertically upwards

Question

I'm using mathpazo to format a document and have just become annoyed that a hat appears to be rendering too close to the letter it's decorating. I'd like to move the hat upwards, but am not sure how to go about doing it.

My LaTeX is just \hat{x}_{t+1}, which renders as:

Is there any way to change this?

Answer 1

\documentclass{article}
\usepackage{mathpazo}
\usepackage{amsmath}   %% come by habit ;)
\begin{document}
    \[
      \hat{x}_{t+1}
    \]
    \[
      \hat{\rule{0ex}{1.2ex}\mkern-3mu x}_{t+1}
    \]
\end{document}
