Hi,

I am studying the algorithm IBK. But I don´t understand how the distance is calculated with an instance that has missing values.
I suspect away with any missing value is assigned zero, regardless of whether the attribute is continuous or nominal .. but I want to confirm.
Another hypothesis is that the algorithm first impute missing values with media..but I don´t sure if so..
I appreciate your help
Alex
