# Nominal2Binomial format

Hi,

I changed a Nominal attribute to Binomial attribute. Now, the binomial attributes have the values, "true" and "false". But, I dont want it to be so. I want 1 and 0 instead of "true" and "false". How do i do this? Is there any option while doing the Nominal2Binolian to take this option? This would be a better way....

Another way is to now change all the dummy variable (say hundredss of them) codings using some mappings or so? Is there a better method for this too?

In general what is the best method to handle this problem?

Many thanks, Shubha
