I would like to list a few formulas which I have done as following:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{enumerate}
\item \textbf{Hommes and in 't Veld AR(1) model:}
\begin{align}
x_t = \frac{1}{R^*}(n_{1,t} \phi_1 + n_{2,t}\phi_2)x_{t-1} + \epsilon_t.
\end{align}
\item \textbf{Weak trend following AR(2) model:}
\begin{align}
x_t = \frac{1}{R^*}((n_{1,t} \phi_1 + 1.4n_{2,t})x_{t-1} - 0.4n_{2,t}x_{t-2}) + \epsilon_t.
\end{align}
\item \textbf{Strong trend following AR(2) model:}
\begin{align}
x_t = \frac{1}{R^*}((n_{1,t} \phi_1 + 2.3n_{2,t})x_{t-1} - 1.3n_{2,t}x_{t-2}) + \epsilon_t.
\end{align}
\item \textbf{General trend following AR(2) model:}
\begin{align}
x_t = \frac{1}{R^*}((n_{1,t} \phi_1 + (1+\phi_3)n_{2,t})x_{t-1} - \phi_3n_{2,t}x_{t-2}) + \epsilon_t.
\end{align}
\end{enumerate}
\end{document}
The problem is that I would like to let these x_t
begin at the same point. Does anyone know how to achieve this?
