However, we advice you to use 0 and 1 for binary variables. Use zero to indicate the absence of a trait and 1 to indicate its presence. For instance, the binary variable ‘having a disease’ should be coded 0 for healthy people and 1 for sick people. In the case of gender, there is no presence or absence of gender, so it doesn’t matter who you assign the 1 and 0 to. You are free to use any other two digits. However, 0 and 1 allow for the clearest interpretation of output. Trust us. Especially when you use the variables in regression, binary variables coded by 0 and 1 will be very easy to interpret.
