Linear regression in discreet space such as color.

Question

Prasanth · Accepted Answer

You cannot use nominal or categorical variables in Linear regression. You have to convert them into binary variables. For example in this case create 1 variable for each color:
Red -> Possible Values (0,1)
Orange -> Possible Values (0,1)
... so on

So If the color is Red, and there are 5 possible colors, then the new variables are 1,0,0,0,0

Tamed0g · Answer

Variables are colors, which can be quantified to integers.

red->1;
orange->2;
yellow->3;
green->4;
.... so on

Then build linear regression model with the integers.
