PCA For categorical features?
<p>In my understanding, I thought PCA can be performed only for continuous features. But while trying to understand the difference between onehot encoding and label encoding came through a post in the following link:</p>

<p><a href="https://datascience.stackexchange.com/questions/9443/when-to-use-one-hot-encoding-vs-labelencoder-vs-dictvectorizor">When to use One Hot Encoding vs LabelEncoder vs DictVectorizor?</a></p>

<p>It states that one hot encoding followed by PCA is a very good method, which basically means PCA is applied for categorical features.
Hence confused, please suggest me on the same.</p>
