I am using this:
\documentclass[12pt,letter paper] {article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{graphicx}
\usepackage[capposition=top]{floatrow}
\usepackage[a4paper,left=25mm,top=25mm,top=25mm,bottom=25mm]{geometry}
\usepackage{amsmath}
\begin{document}
\begin{align*}
{LogTAXREV}_{it} = {\alpha_{0}}+{\beta_{1}LogGDPPC_{it}}
+{\beta_{2}LogTRADE_{it}}+{\beta_{3}LogRESOURCE_{it}}
+{\beta_{4}LogAGRIC_{it}}+{\beta_{5}LogSERVICE_{it}}
+{\beta_{6}LogAGE_{it}}+{\beta_{7}LogPOP_{it}}
+{\beta_{8}LogEDUC_{it}}+{\beta_{9}LogGINI_{it}}
\end{align*}
\end{document}
I get this error: Argument of @fileswith@pti@ns has an extra } on the amsmath usepackage and my equation does not split.
\usepackage[a4paper,left=25mm,top=25mm,top=25mm,bottom=25mm]
Is the geometry package missing? Also not sure about the options for the article class.{geometry}
. First fix that error. You should also remove all those wrong\emph
commands.
