{title:Description}

{pstd}
{cmd:corrtex2} exports a correlation matrix to a publication-quality LaTeX table with the following features:{p_end}

{p 8 8 2}
- Automatically handles Chinese/English variable labels{break}
- Adds significance stars (*** p<0.01, ** p<0.05, * p<0.10){break}
- Generates standalone LaTeX documents compilable with XeLaTeX{break}
- Supports landscape orientation and longtable formats{break}
- Includes observation counts with {cmd:nbobs} option{break}
- Uses LaTeX dcolumn package for perfect decimal alignment{break}
- Compatible with amsmath package for robust star formatting
- Supports by-group processing for subgroup analysis

{title:Options}

{phang}{cmd:file}({it:string}) specifies the output LaTeX file (required).{p_end}

{phang}{cmd:digits}({it:integer}) sets decimal precision (default=3).{p_end}

{phang}{cmd:landscape} formats table in landscape orientation.{p_end}

{phang}{cmd:longtable} uses longtable environment for multi-page tables.{p_end}

{phang}{cmd:append}/{cmd:replace} specifies file handling behavior.{p_end}

{phang}{cmd:casewise} uses casewise deletion for correlations.{p_end}

{phang}{cmd:placement}({it:string}) sets LaTeX table placement (e.g., "htbp").{p_end}

{phang}{cmd:title}({it:string}) specifies custom table title.{p_end}

{phang}{cmd:key}({it:string}) sets LaTeX label prefix.{p_end}

{phang}{cmd:na}({it:string}) specifies missing value representation.{p_end}

{phang}{cmd:noscreen} suppresses on-screen output.{p_end}

{phang}{cmd:nbobs} displays observation counts below correlations.{p_end}

{phang}{cmd:fontsize}({it:string}) sets LaTeX font size (e.g., "\small", "\footnotesize").{p_end}
