I'm looking for a way to align on the left side my math formula and on the right side the \textrm part.
\begin{equation}
w_{t} = \Bigg\{
\begin{aligned}
\log(y_{t}) \textrm{ if } \lambda = 0; \\
(y_{t}^{\lambda} - 1)/ \lambda \textrm{ otherwise }
\end{aligned}
\end{equation}
Is there a simple solution to achieve that ?
