In Titanic dataset, i have a dataset containing Categorical features (such as Cabin, Embark and Sex).
I need to build a linear or polynomial model with multiple variables to predict Survive
. I wish to consider Categorical features as well. Let's say, i can replace all categorical values with a respected numerical value. For example about Sex
column, I can replace: 1
with male
and 2
with female
My question is:
Is it useful to consider a categorical features into a polynomial
or linear model
?
