## One Hot Encoding in Power BI

In a recent post where I described how to implement multiple linear regression in Power BI, I had to perform one hot encoding to make my categorical variable usable by the model. So I decided to make another short post to explain what is hot encoding and how to implement it in Power BI using Power Query. Why do need to perform Hot Encoding? In machine learning or statistical algorithms, many models require to have only numerical input variables. So…
