<blockquote>
<p>Beta regression is commonly used when you want to model <span class="math inline"><em>Y</em></span> that are probabilities themselves.</p>
</blockquote>
<p>This is evident when the value of <span class="math inline"><em>Y</em></span> is a <em>proportion</em> that ranges between 0 to 1. The data points of <span class="math inline"><em>Y</em></span> variable typically represent a proportion of events that form a subset of the total population (assuming that it follows a <a class="auto-link" href="Gamma-and-Beta-Distributions-in-R.html" title="Gamma & Beta Distributions in R: Shape, Scale & Conjugate Priors">beta distribution</a>).</p>
<h2>Use Cases</h2>
<ol style="list-style-type: decimal">
<li>From GasolineYield data: Proportion of crude oil converted to gasoline after distillation and fractionation</li>
<li>Proportion of individuals infected with ‘xyz’ when exposed to various levels of artificial preservative agent.</li>
</ol>
<h2>Example: Gasoline Yield</h2>
<p>Lets predict the gasoline <code>yield</code> as a function of <code>batch</code> and temperature. The example below shows an example implementation of beta regression using the GasolineYield data from <code>betareg</code> package.</p>
