# How are these symbols from Bayesian statistics achieved?

There's a discussion here of two symbols approximating $\coprod$, $\prod$, though these ones are slightly different. They are only presented as part of this image, after the first X on each line:

What is the correct LaTeX for each symbol?

Define the symbols:

\documentclass{article}
\usepackage{amsmath}

\newcommand{\depkern}{\mspace{-9mu}}
\newcommand{\independent}{\mathrel{\bot\depkern\bot}}
\newcommand{\dependent}{\mathrel{\top\depkern\top}}

\begin{document}

$\mathcal{X} \independent \mathcal{Y} \mid \mathcal{Z}$

$\mathcal{X} \dependent \mathcal{Y} \mid \mathcal{Z}$

\end{document}


Adjust the figure in \depkern at will.
