### Bayes' Theorem in \LATEX

I am learning Latex. Using Texnic Center and other similar softwares. I wish that Kile was available on Windows...
Anyways, everytime I start a new file, I have to search for the barebone of the file which needs to be there before anything can be done.
So, here I am collecting some skeleton for latex files:
I think they are free from any (c).

\documentclass[a4paper,11pt]{article}
\usepackage{amsmath} % need for subequations
\usepackage{hyperref} % use for hypertext links, including those to external documents and URLs
\\University}
\begin{document}
\maketitle
\begin{abstract}
Abstract goes here...
\end{abstract}
\tableofcontents{} % comment: just in case... it can be commented
\section{One}
Here we start...
Oh, why not start by writing Bayes Theorem in Latex ?
... we use Bayesian method to infer the model parameters in question. We learn from the available data. The process of arriving at the posterior from the prior in the light of given data can be accomplished by using Bayes' theorem.
As a general statement, we can state Baye's theorem as follows\\
\begin{equation}
\label{eq:bayes}
P(\theta|\textbf{D}) = P(\theta ) \frac{P(\textbf{D} |\theta)}{P(\textbf{D})} ~~~~~|| I,
\end{equation}
where we have adopted Skilling--Gull convention of writing $I$ as the generally accepted term in the conditionals. The data are represented by \textbf{D} and parameters are represented by $\theta$.
\end{document}

Thanks to the Blogger platform which do not convert latex command into symbols. (That was a satire :P )
Note to self: I believe I have seen Gull using the conditional out of bracket... where, where ???
