How do you handle categorical variables in modeling?

<hr>

<h2 class="wp-block-heading">Solution</h2>

Handling categorical variable properly is vital as the wrong method could potentially cause the model to overfit and/or underperform. Here are several factors to consider:

<ul class="wp-block-list">
<li>Type of categorical variable:&nbsp;Nominal or ordinal</li>



<li>Cardinality of the feature:&nbsp;Number of unique categories</li>



<li>Relationship with the target variable:</li>



<li>Model you’re using:
