How to remove unwanted space in beamer?

Question

Here's my code:

\documentclass{beamer}
\usetheme{Berkeley}

\begin{document}

\section{Formula}   
\subsection{Time-varying Coefficients}
    \begin{frame}{Time-varying Coefficients}
    \setbeamercovered{transparent}
    Used to get the degree of ERPT:\\
    $$ERPT = \alert<2>{\beta_0} + \alert<3>{\phi_0}\alert<4>{G(s_t;\gamma,c)}$$
    \begin{description}
        \uncover<2,5>{\item [$\beta_0$] pass-through elasticity}
        \uncover<3,5>{\item [$\phi_0$] pass-through coefficient}
        \uncover<4,5>{\item [$(s_t;\gamma,c)$] logistic transition function driving the nonlinear dynamic}
        \item[]
    \end{description}
    \end{frame}
    \end{document}

if i remove the \item[] the the \item [$(s_t;\gamma,c)$] logistic transition function driving the nonlinear dynamic becomes left-aligned up to the border!

Answer 1

you do not need the \uncover, you have already set transparent option. Use \item<...> instead:

\documentclass{beamer}
\usetheme{Berkeley}

\begin{document}

\section{Formula}   
\subsection{Time-varying Coefficients}
    \begin{frame}{Time-varying Coefficients}
        \setbeamercovered{transparent}
        Used to get the degree of ERPT:\\
        \[ERPT = \alert<2>{\beta_0} + \alert<3>{\phi_0}\alert<4>{G(s_t;\gamma,c)}\]
        \begin{description}
            \item<2,5>[$\beta_0$] pass-through elasticity
            \item<3,5> [$\phi_0$] pass-through coefficient
            \item<4-> [$(s_t;\gamma,c)$] logistic transition function driving the nonlinear dynamic
        \end{description}
    \end{frame}
\end{document}
