transforming categorical values to dummy
I am a student and for one of my projects in predicting house prices, I want to use regression method to predict the house prices. But as usual there are some categorical attributes in my data sets, which I would like to transform them to dummy variables (there are 3 different types of data type in my attributes, namely; integer, polynomial and binominal) before any further action. I was wondering whether you could help me in this regard and tell me how and with what operator can i to transform each of these attributes to dummy variables?
with best regards
