Hi Sean!
I guess the low-level interface means using the commands
\voffset, ...,
\evensidemargin etc. That's stone age TeX and can lead to issues easily. It's better to use the
geometry package and the
\geometry command with options.
Have a look at this link, about why and how to provide code:
minimal working example
\intertext works within an
align environment. You used it outside, that's why it doesn't work.
align* is not useful here since there's no alignment.
Furthermore, the matrix has more than 10 columns, that's the default maximum. You can raise it, such as by setting
\setcounter{MaxMatrixCols}{11}.
Working code:
Code: Select all
\documentclass{article}
\usepackage{amsmath}
\setcounter{MaxMatrixCols}{11}
\begin{document}
\begin{align*}
\intertext{The vector of parameters to be estimated by maximum
likelihood is as follows:}
\end{align*}
\[
\boldsymbol{\theta}_{2} = \begin{bmatrix}
a_{y,1} & a_{y,2} & a_{r} & a_{0} & a_{g} & b_{\pi} & b_{y} & g
& \sigma_{\Tilde{y}} & \sigma_{\pi} & \sigma_{y^{*}}
\end{bmatrix}
\]
\end{document}
I used the
align* environment only to show how
\intertext works. It is for text between several lines within a multi-line formula or equation.
