We can add coloured boxes with text or mathematics into a LaTeX beamer presentation which is particularly useful if we have definitions, theorem or computer code to highlight this information that may not be so accessible within a paragraph of text.

The easiest way to create a box is to use the various pre-defined environments such as definition:

\begin{definition}
The simple linear regression model describes the relationship between
a response variable and a single explanatory variable.
\end{definition}

We might want to create a box with our own title in which case the exampleblock environment can be used with the new title as an argument to this environment:

\begin{exampleblock}{Linear Regression Model}
$Y_{i} = \beta_{0} + \beta_{1} X_{i} + \epsilon_{i}$
\end{exampleblock}
